摘要

Submersible pumps are universally used in recent days. These pumps which are immersed in the working fluid, work on Forced vortex principle. Impeller shape optimization for a specific purpose has its effect on the H-Q curve of the pump, as stated by 2nd law of thermodynamics. Hence this research work was focused on the improvement of duty head of the pump without changing the outlet & inlet diameter of the impeller. This optimization was done by means of minimising the head losses that occur in the impeller. Optimization was carried out using optimization algorithms like GA, SA, PS etc and the optimized values are used for design of new impeller. The optimized result was tested using CFD with common turbulence models. The resulting design was casted and experimentation was carried out.
