Robert Bosch Engineering & Business Solutions - Case Study
A multiphase simulation was performed of an engine oil lubrication vane pump. Cavitation becomes more harmful when the vapor bubbles move toward a high-pressure zone inside the pump, causing implosion and shock waves. Moreover, cavitation formation reduces the pump’s efficiency, which is directly interconnected with the engine’s lubrication and fuel efficiency. The objective was to identify the zones that are prone to cavitation using a validated simulation approach.
