Numerical Simulation of FSI in the Design Process for a New Axial Hydraulic Pump

From 2012 Automotive Simulation World Congress: Gdansk University used numerical simulation to develop a high-pressure hydraulic axial pump for applications that demand high power. Its unique feature is the total independence of a pressure-switching mechanism, which saves weight and enables control by computer. Researchers found that when the pressure changes from high to low via a commutative bushing, harmful pressure peaks occurred. A compensation chamber between the high- and low-pressure areas was introduced. Interdisciplinary numerical simulation was used to find the optimal layout of the chamber and pump. The hydraulic oil and the piston movement were modeled in ANSYS Fluent.
