A REVIEW PAPER ON DEVELOPMENT OF IMPELLER OF CENTRIFUGAL PUMP USING COMPUTATIONAL FLUID DYNAMICS

Nowadays, the centrifugal pumps became very popular because of recent development of high speed electric motors, steam turbines etc.Centrifugal pumps can be single-stage or may be multistage pumps. It depends upon the number of impellers used in the pump. Single stage pump consists of only one impeller while in multistage pumps the impellers are mounted in the series in pumps. These Centrifugal pumps can be analyzed by software code like Computational Fluid Dynamics (CFD).This CFD tool or code helps to optimize the pump performance. The complex internal flows are to be predicted with the CFD code. The optimized pumps are used for various applications like drainage and drinking water system, chemical Industries- Catalyst transfer, acid transfer and neutralizing, waste water/Chemicals- Industrial effluents, purifying water, in process industriespaper pulp, chemicals, and pharmaceuticals etc.
