Formatted abstract
One of the important technologies for breaking rock in mining industry is by using a submerged cavitating water jet. This thesis investigates the phenomenon of cavitation in submerged water jet by attempting to correlate it with dimensional analysis. Based on experimental data obtained from a past researcher, the data was analysed to find relationship between cavitation damage and the operating condition of the submerged water jet. Several assumptions and hypotheses have been made that led to the development of a dimensional analysis tool that would be used to predict the location of maximum cavitation damage. The validity of this tool was analysed and compared with the experimental data. Other factors that contribute to cavitation damage were also investigated in this thesis. Despite the great number of assumptions made and the complex behaviour of cavitating water jet, the outcome given by the dimensional analysis tool matches the experimental data. Apart from that, possible sources of error are also identified with regards to the assumptions and analysis of the thesis. Also, possible areas for further investigation are discussed.
