摘　　要：使用Fluent软件对压缩机缸内气体流场进行模拟研究,构建气缸的三维模型,以连续性、能量和动量方程作为基本控制方程,设置动网格基本参数,进而得到气流在气缸内的流场变化过程。分析缸内气体的流动状态包括压力、温度、湍动能等参数的微观变化情况,为优化改进压缩机性能提供依据。Using the fluent software to simulate the gas flow field in cylinder of compressor, build three - dimensional model of cylinder. With continuity, energy and momentum equation as the basic control equation, basic parameters of dynamic mesh were set up and the airflow in the flow field inside the cylinder change process was obtained. Analysis of the gas flow conditions, including changes in pressure, temperature, and other parameters of the turbulent kinetic energy, will provide a basis for optimizing compressor performance improvements.
