实际混合气体状态变化对压缩机热力计算的影响

摘要

As the condition of the actual gas mixture changes, the compressibility coefficient of each constituent will change differently, which leads to a redistribution of the volumetric percentage composition, and changes in the properties and thermodynamic parameters of the mixture.This paper analyzed the influence of these changes on thermodynamic calculation and then put forth a correction method.%实际混合气体状态改变时,组成该混合气体的各气体压缩性系数发生不同变化,导致混合气体的容积百分比重新分配、综合物性参数和热力学参数发生变化.本文分析了这些变化对压缩机热力计算的影响,并提出修正方法.
