摘要： 基于动网格方法建立了滚动活塞压缩机泵腔流动的三维瞬态数值模拟模型,模拟结果与理论工作循环对比表明该模型反映了滚动活塞压缩机工作的基本过程,可以用于泵腔流场的研究.模拟了气体在泵腔内的流动过程,给出了直观丰富的泵腔流动信息,对泵腔内的流动现象和流场分布进行了分析,指出了压缩机吸气、压缩和排气时流场的主要特征.研究结果为滚动活塞压缩机泵体结构的优化提供了理论依据,并为整机流场的进一步研究提供了重要参考.

Abstract: Using a moving mesh method, a three-dimensional transient numerical simulation model for a rolling piston compressor chamber was established. Compared with a theoretical work cycle, the numerical results indicated that the model reflected the main process of a rolling piston compressor, and can be used to study a pump chamber flow field. Gas flow in a pump chamber was simulated, providing considerable detailed information of the pump chamber flow field. Flow phenomena and flow field in the pump chamber were analyzed, and primary characteristics of the flow field during compressor intake, compression, and exhaust were determined. The results provide a basis for structural optimization and further study in rolling piston compressors.
