Structural Design and Simulation Analysis of Ejector Used in Automotive Power Steering Oil Discharge Equipment

Abstract

The structure of ejector used in automotive power steering oil discharge equipment is designed in accordance with the theory of gas-liquid ejector.The two important parameters of the ejector are elected respectively to five values and then 25 ejector models are obtained by the permutations and combinations.The ejector’s CFD model is created by Fluent module of Ansys,then it is divided into a grid and analyzed. Analyse its pressure distribution and velocity vector, which provides the optimal size for the manufacture of the ejectors and a theoretical basis for experiment.
