CFD Analysis of C. I. Engine Cooling Water Pump of car

To study behaviour of flow in cooling water pumps, we done extensive search and gone through numerous research paper and blogs.We found that many researchers carried out their analysis on other cooling system components like radiator, cooling water jacket and fans. But it is very difficult to find researchers worked on cooling water pumps. However cooling system consists of centrifugal pump which is widely used in other industry. After reviewing all research paper on centrifugal pumps we found that most of the problems are related to cavitation and low efficiency. Some researchers give importance to improvement of blade angle and blade design to reduce cavitation effect while some researches concentrates on efficiency of the pump irrespective of cavitation effect mostly in the industry where cavitation effect is negligible. 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 role of centrifugal water pump in automobile engine cooling system and to obtain relation between pump geometry and pump flow characteristics.
