摘要(Abstract):

采用专业的运动机械CFD仿真软件Pump Linx对包含压缩腔、气动阀门在内的滚动转子压缩机整机进行了瞬态仿真分析,通过软件内置的转子模块和阀门模块快速实现了压缩机整机的网格划分和动网格设置。通过仿真获得了压缩机流量、温度、COP、压力以及阀门运动情况,并将出口流量和温度与试验结果进行了对比,吻合良好,为滚动转子压缩机的整机性能预测和优化设计提供了依据。
The rolling piston was studied in this paper using transient simulation analysis based on the Pump Linx which is professional tool in the field of rotating machinery. In order to solve the difficulty like generating mesh and controlling mesh movement,the rolling piston module and valve module in Pump Linx were used. From the simulation,mass flow rate,temperature,COP,pressure and valve movement can be obtained,of which the mass flow rate and temperature fit the experimental data well. The method introduced in this paper will be appropriate for performance prediction and optimization of the rolling piston compressor.
