THE PERFORMANCE OPTIMIZATION OF ROLLING PISTON COMPRESSORS BASED ON CFD SIMULATION

In this paper, the simulation of rolling piston compressor is established using Star-CD, a general computational fluid dynamics (CFD) software. Based on the result, the P-V diagram of compressor’s working process and all kinds of factors influencing the compressor’s overall efficiency are analyzed deeply, then several optimum projects are put forward in order to improve the compressor’s overall efficiency. Finally, all the former projects are proved by theoretical CFD simulation respectively.
