Abstract

In view of the complex and time changing characteristics of the fluid domain in the twin screw compressor, and in order to study it’s performance characteristics in detail, used STAR CCM＋software to do the computational fluid dynamics (CFD) analysis, and the experimental platform was built to verify the accuracy of the simulation results. By comparing the pressure values of the simulated monitoring points and the experimental measured points corresponding to them, both of them have good consistency in the pressure value and the period of pressure fluctuation.
