Unfortunately, little is understood about how to polish a micro bore and how to assess its inner wall quality because it is difficult to access the micro bore for either polishing or measurement. This article reports on a feasibility study of the abrasive flow polishing of micro bores of 260 similar to 500-mum diameters and 25 similar to 50 length/diameter ratios for both metal and ceramic materials. An abrasive flow polishing machine was designed and built with turbulent flow characteristics. Polishing of steel S45C bores of 400- and 500-mum diameters, stainless steel 304 bores of 500-mum diameter, and zirconia bores of 260-mum diameter was conducted. Surface roughness and topography of the polished inner walls of micro bores were characterized using profilometry and optical interferometry from the three-dimensional point of view. Significant reduction in surface roughness of the micro bore inner walls has been made in the polishing processes. The results indicate that it is feasible to apply the abrasive flow polishing technology for metal and ceramic micro bores of diameters of 260 mum or larger and the length/diameter ratios of 25 or higher. It is found that surface roughness of the polished micro bore inner walls decreases with an increase of the abrasive flow passes. 2008-01-25T16:12:27Z Yin, L og Ramesh, K og Wan, S og Liu, XD og Huang, H og Liu, YC http://espace.library.uq.edu.au/view/UQ:75726 In this paper a new structural model is presented to describe the evolution of porosity of char during the gasification process. The model assumes the char structure to be composed of bundles of parallel graphite layers, and the reactivities of each layer with the gasification agent are assumed to be different to represent the different degree of heterogeneity of each layer (i.e. each layer will react with the gasification agent at a different rate). It is this difference in the reactivity that allows micropores to be created during the course of gasification. This simple structural model enables the evolution of pore volume, pore geometrical surface area and the pore size distribution to be described with respect to the extent of char burn-off. The model is tested against the experimental data of gasification of longan seed-derived char with carbon dioxide and it is found that the agreement between the model and the data is reasonably satisfactory, especially the evolution of surface area and pore volume with burn-off. 2007-08-15T06:01:33Z Junpirom, S. og Do, D.

The rig uses a crank eccentric mechanism to flex the blade by a constant displacement in the flapwise direction for each load cycle. A yearly fatigue-loading spectrum for the blades has been developed from using short-term detailed aeroelastic and wind measurements, results from a detailed finite element model of the blade and averaged long-term wind data form the Australian Bureau of Meteorology. This spectrum contained over 200 load levels covering R ratios from 0 to 0.9. An equivalent damage spectrum has been formulated to minimise the number of load levels within the spectrum without compromising the amount of damage done to the blade structure. Results of fatigue testing indicate that predictions are close to the measured fatigue life of the blade. The stress distribution in fatigue critical areas of the blade during testing was found to be similar to the expected stress distribution under normal operational condition. 2004-12-17T00:00:00Z Epaarachchi, Jayantha A. og Clausen, Philip D. http://espace.library.uq.edu.au/view/UQ:104075 2007-08-23T22:02:45Z Walther, J. og Radcliffe, D F http://espace.library.uq.edu.au/view/UQ:138108 2008-05-09T11:34:31Z Walther, J. og Radcliffe, D.F. http://espace.library.uq.edu.au/view/UQ:62939 Convergent beam Kikuchi diffraction was used to accurately determine the orientation relationships (ORs) between austenite and martensite, and between austenite and granular bainite in two Fe-Ni-Mn-C alloys.

Based on the obtained results, an improved thermomechanical control process (TMCP) was proposed, which could produce a mixed microstructure dominated by acicular ferrite. Results indicated that an increase in the cooling rate could improve the percentage of acicular ferrite in the final microstructure under the present experimental conditions. Furthermore, the acicular ferrite dominated microstructure could be obtained by a two stage controlled rolling in the austenite recrystallisation region plus the non-recrystallisation region and controlled cooling at a cooling rate of 30 K s(-1). 2008-01-25T15:56:03Z Zhao, MC og Shan, YY og Xiao, FR og Yang, K http://espace.library.uq.edu.au/view/UQ:122223 The transformation of super-cooling austenite in a commercial pipeline steel was investigated by measuring the continuous cooling transformation (CCT) diagram and the hot simulation test. Based on the obtained results, a thermo-mechanical control process (TMCP) has been proposed, which can obtain a mixed microstructure mainly consisted of acicular ferrite, and the detailed features of acicular ferrite are also analyzed. Results indicate that the increase of cooling rate can increase the content of acicular ferrite in the final microstructure of the pipeline steel under the present experimental conditions. 2008-01-25T15:31:16Z Zhao, MC og Shan, YY og Qu, JB og Xiao, FR og Zhong, Y og Yang, K http://espace.library.uq.edu.au/view/UQ:120596 2007-12-12T11:51:44Z Williams, David J. http://espace.library.uq.edu.au/view/UQ:10602 Acid mine drainage (AMD) and minesite salinity are arguably the most serious threats posed to the environment by open cut mining and mineral processing. AMD arises when sulphur, usually in the form iron sulphide (pyrite) contained in the ore and/or waste materials, is exposed to oxidation, the products of which are leached out as acid. As the pH of the system drops, bacteria begin to catalyse the chemical reaction. Open cut mining and mineral processing also lead to the storage of water on the surface where evaporation raises the salinity of the water. This paper reviews some of the acid mine studies done in recent years, suggests engineered solutions to mitigate the problem and shares some local experiences of AMD and minesite salinity. 2004-04-02T00:00:00Z Williams, David J. http://espace.library.uq.edu.au/view/UQ:100814 2007-08-23T19:45:38Z Song, N. og Meehan, P.

S. http://espace.library.uq.edu.au/view/UQ:66395 The effect of a gas flow field on the size of raceway has been studied experimentally using a two-dimensional (2-D) cold model. It is observed that as the blast velocity from the tuyere increases, raceway size increases, and when the blast velocity is decreased from its highest value, raceway size does not change much until the velocity reaches a critical velocity. Below the critical velocity, raceway size decreases with decreasing velocity but is always larger than that for the same velocity when the velocity increased. This phenomenon is called raceway hysteresis. Raceway hysteresis has been studied in the presence of different gas flow rates and different particle densities. Raceway hysteresis has been observed in all the experiments. The effect of liquid flow, with various superficial velocities, on raceway hysteresis has also been studied. A study of raceway size hysteresis shows that interparticle and particle-wall friction have a very large effect on raceway size. A hypothesis has been proposed to describe the hysteresis phenomenon in the packed beds. The relevance of hysteresis to blast furnace raceways has been discussed. Existing literature correlations for raceway size ignore the frictional effects. Therefore, their applicability to the ironmaking blast furnace is questionable. 2007-08-15T02:03:35Z Sarkar, S. og Gupta, G. S. og Litster, J. D. og Rudolph, V. og White, E. T. og Choudhary, S.

Results from a range of conditions with helium and argon driver gases are reported. Significant performance gains were achieved in some test cases. Heat losses are shown to have a strong effect on driver processes.

This is a piece of very unique work. Normally people think that the order of adsorption of alkali metals on carbon should be either Li>Na>K or K > Na > Li. But our study shows that Na adsorption is the weakest one. We are the first to report this interesting phenomenon and a convincing explanation is also provided based upon the electronic structures of graphite and alkali metals. 2006-04-27T14:40:11Z Zhu Z H og Lu G Q http://espace.library.uq.edu.au/view/UQ:97579 2007-08-24T01:22:25Z Balliu, N.

Temperature sensitive liquid crystals are used to measure the characteristic increase in heat transfer coefficient through the transitional region on a uniformly heated surface. Shear sensitive liquid crystals are used to detect the high surface shear stress at the end of transition. The objective of this work was to assess the suitability of these techniques for transition detection in low speed flows. Both techniques can be used to locate transition and to obtain quantitative information about surface phenomena, but the destabilizing influence of heating in the first technique must be considered. 2006-01-03T00:00:00Z Mee, D.

F. og O'Moore, L. http://espace.library.uq.edu.au/view/UQ:60005 The Australian Coal Industry Research Laboratory (ACIRL) furnace is scaled to simulate slagging and fouling in operating boilers. This requires that the gas and target temperatures, the heat flux, and the flow pattern be the same as those in real boilers. The gas and target temperatures are maintained by insulating the wall and cooling the target respectively. The flow pattern of a small burner cannot be the same as a large furnace. However, this flow pattern is partially compensated for by placing the slagging panels in three vertical locations. The paper develops the models of radiant heat transfer from the flame to the deposits both in pilot-scale and full-scale furnaces. They are used to compare the effective radiant heat transfer of the pilot- and full-scale furnaces. The experimental data both from the pilot- and full-scale furnaces are used to verify the incident heat flux and temperature profiles in the pilot- and full-scale furnaces. The results showed that the thermal condition in the pilot-scale furnace meets the requirements for studying the slagging regarding the gas temperature and the incident heat flux, particularly for the panel #1. The gas temperature in the convective section also meets the requirement for studying the fouling. 2007-08-14T16:12:20Z Su, Shi og Pohl, John H. og Holcombe, Don og Hart, John A. http://espace.library.uq.edu.au/view/UQ:120611 Mine tailings are commonly disposed of in slurry form by subaerial deposition from a pipeline. Coarse mine wastes may be combined with the tailings. At discharge points along the pipeline, the slurry forms sloping beaches whose profiles have a direct bearing on the volume of tailings that can be stored in a given impoundment. The profiles of such beaches are described well by both a power law equation and an exponential equation that incorporate different profile concavity parameters. These two equations, which have been compared previously on the basis of very limited data, are re-examined here on the basis of a much-expanded data set. The exponential equation, which has a theoretical basis, fits the profiles of most beaches slightly better than the empirical power law equation. On average, it gives slightly higher estimates for the volume of tailings that can be stored in a given impoundment. A simple method of conversion from -one profile equation to the other is described. 2007-12-12T14:22:20Z Morris, Peter H. og Williams, David J. http://espace.library.uq.edu.au/view/UQ:97543 2007-08-24T01:19:58Z Boot, D og Cooper, P og St John, D. H. og Dahle, A. K. http://espace.library.uq.edu.au/view/UQ:65720 This paper presents a comprehensive study of sludge floc characteristics and their impact on compressibility and settleability of activated sludge in full scale wastewater treatment processes. The sludge flocs were characterised by morphological (floc size distribution, fractal dimension, filament index), physical (flocculating ability, viscosity, hydrophobicity and surface charge) and chemical (polymeric constituents and metal content) parameters. Compressibility and settleability were defined in terms of the sludge volume index (SVI) and zone settling velocity (ZSV). The floc morphological and physical properties had important influence on the sludge compressibility and settleability. Sludges containing large flocs and high quantities of filaments, corresponding to lower values of fractal dimension (D-f), demonstrated poor compressibility and settleability. Sludge flocs with high flocculating ability had lower SVI and higher ZSV, whereas high values of hydrophobicity, negative surface charge and viscosity of the sludge flocs correlated to high SVI and low ZSV. The quantity of the polymeric compounds protein. humic substances and carbohydrate in the sludge and the extracted extracellular polymeric substances (EPS) had significant positive correlations with SVI. The ZSV was quantitatively independent of the polymeric constituents. High concentrations of the extracted EPS were related to poor compressibility and settleability. The cationic ions Ca, Mg, Al and Fe in the sludge improved significantly the sludge compressibility and settleability. (C) 2003 Elsevier Science B.V.

Our background is Kanger-Lindahl-P\"orn account of organised interaction, which describes this interaction within a multi-modal logical setting. This work focuses in particular on the notions of counts-as link and on those of attempt and of personal and direct action to realise states of affairs. We show how standard Defeasible Logic can be extended to represent these concepts: the resulting system preserves some basic properties commonly attributed to them. In addition, the framework enjoys nice computational properties, as it turns out that the extension of any theory can be computed in time linear to the size of the theory itself. 2007-02-02T00:36:13Z Governatori, Guido og Rotolo, Antonino http://espace.library.uq.edu.au/view/UQ:8739 Calculations have been performed for the inviscid hypervelocity flow of nitrogen past a 15 degree semi-angle sharp cone at an incidence of 30 degree, at an enthalphy sufficiently high to produuce dissociation/recombination chemistry downstream of the bow shock wave. A spatially second-order-accurate EFM (Equilibrium Flux Method) scheme for the numerical solution of the inviscid Euler equations was used, combined with the Lighthill-Freeman model of the non-equilibrium ideal dissociating gas. The computations have been sued to gain an understanding fo the interaction between the ags dynamics and the finite-rate chemistry. Inviscid flow has been considered to ensure that the only physical length scales in the flow are those associated with the chemical reactions. It was found that a chemical length scale L_s, based on the local dissociation length behind the shock on the windward plane of symmetry is an important governing parameter of the flow. However, as the flow length-scale becomes large and the flow approached the limiting case of equilibrium chemistry, L_s is not the dominant chemical length-scale, particularly in the leeward flow which contains a shock-vortex structure. A simple modelling technique has been used to determine a more appropriate length scale L_r for the leeward flow, based on the equilibrium conditions behind the leeward cross-flow shock. 2006-01-27T00:00:00Z Macrossan, Michael N. og Pullin, Dale I. http://espace.library.uq.edu.au/view/UQ:165546 2009-03-02T13:35:06Z Cleary, M. J. og Kent, J. H. og Bilger, R. W. http://espace.library.uq.edu.au/view/UQ:34786 This paper describes U2DE, a finite-volume code that numerically solves the Euler equations. The code was used to perform multi-dimensional simulations of the gradual opening of a primary diaphragm in a shock tube. From the simulations, the speed of the developing shock wave was recorded and compared with other estimates. The ability of U2DE to compute shock speed was confirmed by comparing numerical results with the analytic solution for an ideal shock tube. For high initial pressure ratios across the diaphragm, previous experiments have shown that the measured shock speed can exceed the shock speed predicted by one-dimensional models. The shock speeds computed with the present multi-dimensional simulation were higher than those estimated by previous one-dimensional models and, thus, were closer to the experimental measurements. This indicates that multi-dimensional flow effects were partly responsible for the relatively high shock speeds measured in the experiments. 2007-08-13T10:25:04Z Petrie-Repar, PJ og Jacobs, PA http://espace.library.uq.edu.au/view/UQ:174454 This paper investigates the feasibility of plate-wave diffraction tomography for the reconstruction of flexural inhomogeneities in plates using the results of computer simulation studies. The numerical implementation of the fundamental reconstruction algorithm, which has recently been developed by Wang and Rose [C.H. Wang, L.R.F. Rose, Plate-wave diffraction tomography for structural health monitoring, Rev. Quant. Nondestr. Eval. 22 (2003) 1615–1622] is investigated addressing the essential effects of applying the discrete form of the Fourier diffraction theorem for solving the inverse problem as discussed by Kak and Slaney [A.C. Kak, M. Slaney, Principles of Computerized Tomographic Imaging, IEEE Press, New York, 1988] for the acoustic case, viz. diffraction limited sensitivity, influence of weak scatterer assumption, damage location and scatter field data processing in time and Fourier space as well as experimental limitations such as finite receiver length and limited views. The feasibility of the imaging technique is investigated for cylindrical inhomogeneities of various severities and relative position within the interrogation space and a normal incident interrogation configuration. The results show that plate-wave diffraction tomography enables the quantitative reconstruction of location, size and severity of plate damage with excellent sensitivity and offers the potential for detecting corrosion thinning, disbonds and delamination damage in structural integrity management applications. 2009-04-08T08:51:03Z Rohde, A. og Veidt, M. og Rose, L.

The prototype system is developed by employing blackboard architecture and a commercial shell VISUAL RULE STUDIO. Its present scope covers design of three types of liquid-retaining structures, namely, a rectangular shape with one compartment, a rectangular shape with two compartments and a circular shape. Through custom-built interactive graphical user interfaces, the user is directed throughout the design process, which includes preliminary design, load specification, model generation, finite element analysis, code compliance checking and member sizing optimization. It is also integrated with various relational databases that provide the system with sectional properties, moment and shear coefficients and final member details. This system can act as a consultant to assist novice designers in the design of liquid-retaining structures with increase in efficiency and optimization of design output and automated record keeping. The design of a typical example of the liquid-retaining structure is also illustrated. (C) 2003 Elsevier B.V All rights reserved. 2007-08-15T01:30:35Z Chau, K.

These flows are turbulent and velocity measurements must be conducted at high frequency to resolve the small eddies and the viscous dissipation process. The acoustic Doppler velocimetry (ADV) is designed to record instantaneous velocity components at a single-point with such a relatively high frequency. The ADV signal strength may provide further information on the instantaneous suspended sediment concentration (SSC). Laboratory and field experiences demonstrated that the ADV metrology is a robust technique well-suited to steady and unsteady turbulence measurements in open channel flows. But the ADV outputs must be processed carefully while the calibration of an ADV for SSC measurements is critical. Laboratory and field experiments with turbulence measurements in open channels are discussed herein. Past experiences showed unequivocally that turbulence properties should not be derived from unprocessed ADV signals and that even classical "despiking" methods were not directly applicable to many field and laboratory applications. A successful data analysis relies often upon solid practical experiences with the instrumentation, its capabilities and its limitations. 2008-11-28T14:58:54Z Chanson, Hubert http://espace.library.uq.edu.au/view/UQ:138211 2008-05-12T10:52:36Z Townson, P. og Murthy, D.N.P. http://espace.library.uq.edu.au/view/UQ:75586 This review aims to provide a foundation for the safe and effective use of magnesium (Mg) alloys, including practical guidelines for the service use of Mg alloys in the atmosphere and/or in contact with aqueous solutions.
