摘　　要：以规律化流场特性作为缓冲器优化设计的新思路,研究切向进口缓冲器及径向进口缓冲器在压缩机不同出口压力条件下对压力波动的减弱效果。做5组压缩机不同进出口压力的实验,运用Fluent建立缓冲器及相关接管模型,根据实验所测的缓冲器进出口压力作为边界条件进行数值模拟计算。分析不同进口缓冲器内部流场,比较各自流场流体迹线规律特点,建立流体微团流动混合模型,初步提出混合模型的表达式,得出影响减脉性能的流场要素。Optimizing the property of the buffer by using the characteristic of the regular flow field, discussing the effect of the tangential inlet buffer and radial buffer with different outlet conditions. The reason that affects buffer performance can be gotten through the analysis of internal flow flied and fluid path lines of different buffers. Five groups experiments of different outlet pressure of the compressor are used to provide boundary conditions for Fluent simulation calculation. A flow hybrid model of fluid micro mass is established, and the expression of the mixed model is proposed.
