EFFECT OF CASING GEOMETRY ON PERFORMANCE OF CENTRIFUGAL PUMP : AN STUDY FOR SHAPE OF CASING

The performance of a centrifugal pump can be measured experimentally as well as with the help of an advanced numerical technique called computational fluid dynamics (CFD). In the present work the performance of a centrifugal pump is analyzed by CFD tool to compare the three types of volute geometry. The results of numerical flow simulations are discussed by plotting graphs of various flow parameters like velocity pressure pressure coefficient efficiency power head etc. with respect to discharge.
