DESIGN & OPTIMIZATION OF CENTRIFUGAL PUMP USING ANSYS'& GENETIC ALGORITHM

Abstract

Centrifugal pump is the most widely used pump in the world today as it has simple design, with wide range of capacity and head. The ability of hydraulic structure or element to conduct fluid with minimum energy loss is the most important property of a pump system. The present work deals with the Computation Fluid Dynamics study of the hydrodynamic characteristics (i.e. pressure and velocity) of a centrifugal pump using Ansys®-CFX and optimize the design with the help of pattern search method (i.e. Genetic Algorithm) using MATLAB®. In this work the pump is designed analytically with the use of characteristics curve which are further used in the validation of the design obtained by Vista-CPD. The pump is designed to obtain maximum value of hydraulic efficiency at the (BEP) Best Efficiency Point. The work includes CFD simulation of centrifugal pump in baseline & optimized design variables. The optimized parameters have been evaluated for the design using genetic algorithm.
