Automotive Hydraulic Pump Simulation

Automotive pumps take two forms: hydraulic and centrifugal. Hydraulic pumps are positive displacement pumps, with fl ow rate a direct function of rotational velocity. In the automotive industry, hydraulic pumps include gear pumps, gerotor pumps, vane pumps and piston pumps. Vehicle applications include fuel pumps, super-charging pumps, power-steering pumps, automatic transmission pumps and many others. Hydraulic pumps must be designed to avoid leakage and cavitation. Additional objectives include minimizing fuel noise and maximizing volumetric efficiency.
