1. to introduce the numerical method "Computational Fluid Dynamics (CFD) techniques", to the simulation of flow problem in chemical engineering field.
2. to simulate the flow within hydrocyclone. The results will allow an assessment of the effect of hydrocyclone geometry on the separation flow zone.
3. to use the methodology to design hydrocyclone for yeast separation in brewing industry, and to test the prediction by fabricating the novel hydrocyclone design and testing its performance.
