This text regard Gas-Liquid Cyclone(GLCC) separator of air compressor as research object,adopt Computational Fluid Dynamics(CFD) to simulate the flow field go on GLCC.The purpose is to probe into fow characteristic pressure distribution of separator under primitive structure and improved structure.This text has introduced the basic theory of the GLCC,including mathematical model and main parameter such as separation efficiency&pressure loss&cut siza,etc,providing some current research situations and experie...
