Abstract

Flow characteristics of an automotive oil pump of gerotor type have been investigated numerically. For the simulation of a gerotor whose inner and outer rotors rotate at different speeds, node expansion and contraction method was adopted. ASI (Arbitrary Sliding Interfaces) method was also applied at interface between rotating gerotor and stationary volute. Studied are the flow rates depending on various gerotor in the gap are also studied. The present results showed good agreement with the experimental data.
