Formatted abstract
Airlift pumps are used extensively throughout the chemical, mining and oil industries for the removal of a variety of different substances from corrosive, poisonous, or viscous liquids to conveying slurries. Although they are easy to operate and implement within a wide range of applications the theoretical analysis is complex, and there are limited theoretical models available for multiphase system analysis.

This thesis has developed a simplified theoretical model that can be used to predict the performance of an airlift pump, and in particular the water entrainment velocity. The theoretical model was been numerically tested against raw experimental data with promising and realistic results. The affect of varying chosen parameters has also numerically tested where expected results were obtained. The theoretical model was then used to predict an airlift pumps performance when applied to a CRC Mining project known as Tight Radius Drilling (TRD). It predicted a water entrainment velocity of 0.53 m/s.

Experiments performed using an airlift pump within the TRD geometry is required to analyse how accurate the theoretical models prediction of the water entrainment velocity is. A comparison against Computational Fluid Dynamics (CFD) would also be beneficial to clarifying the limitations to the developed theoretical model.
