Numerical Simulation of Labyrinth Oil and Gas Separator in Vehicle Engine
Main Article Content
Abstract
The working process of oil and gas separator is a very complex gas-liquid two-phase separation movement; it is difficult to obtain internal flow condition using analytical method. In this paper, with DPM, SIMPLE algorithm and random walk model, velocity distribution, pressure distribution, oil droplets motion trajectory and separation efficiency were analyzed by numerical simulation method. This analysis is helpful to understand flow law of gas-liquid two-phase fluid in oil and gas separator，and then optimize separator structure, short its development cycle, which has important application value in engineering.
