To study about the behaviour of flow inside the cooling water pump, we done extensive search and gone through number of research papers and blogs. Many researchers carried out their analysis on cooling system components like radiator, coolant, water jackets, fin materials etc. but it is very difficult to find the researcher that works on cooling water pump. Cooling system consist centrifugal pump which is widely used in other industries. After reviewing some research papers on centrifugal pumps we found that most of the problems are related to cavitation and efficiency. Computational Fluid Dynamics (CFD) analysis is one of the advance tool used to understand the behaviour of fluid. A detailed CFD analysis is done to carry out the flow pattern inside the impeller which is an active component of pump. After analyzing some old water pumps of various vehicles we found that major problem that pump is facing is due to cavitation effect on blades at High RPM. This research is aimed to analyze the flow behaviour by modifying the impeller design by choosing blade angle.CFD analysis is done using ANSYS CFX software.
