摘　　要：主要针对某型旋叶式压缩机的排气过程进行研究,基于旋叶式压缩机的工作循环为一个理论循环的假设建立了其工作过程的一个数学模型,并采用有限体积法通过CFD(计算流体力学)软件Fluent对该压缩机的排气基元进行模拟仿真。最终得出压缩机排气过程内部的声功率分布情况,及排气口附近的噪声声压谱图。The exhausting process of a rotary vane compressor was discussed.The modle is established on the suppose the working process is a theoretical cycle.Based on the modle,the exhausting process was simulated through the Fluent software by the the finite volume method.Finally,the paper draw the compressor internal sound power distribution of process exhaust,and the noise sound spectra near by the vent.
