Numerical Simulation for Feed-Oil Pump of Aero-Engine

Abstract:

With reference to cavitation phenomena in the feed-oil pump of aero-engine, a numerical method is presented in this paper to analyze operating performance of pump. Local re-meshing model is introduced to update the computational mesh when the gear teeth in mesh depart each other. Also, the full cavitation model is applied to simulate the flow field, the mass transfer between oil and vapor at low pressure producing region. The performance of a typical feed-oil pump is predicted to evaluate the altitude influence. Results show that more oil vapor is produced at higher altitude. Meanwhile, the leakage mass is mainly depended on the pressure drop.
