摘要
针对离心式压缩机模型级进行了数值模拟,与试验结果对比验证了计算模型的正确性,用无叶扩压器代替叶片扩压器在相同的边界条件下进行流场数值模拟,根据模拟结果对比分析了两种情况下叶轮内部的流动特征,揭示了叶片扩压器和无叶扩压器对离心式压缩机级内流场的影响规律。
A centrifugal compressor stage model is numerically studied. The result agrees with the experiment result. A numerical simulation is preformed by replacing vane diffuser with vaneless diffuser with the other boundary conditions unchanged. The flow conditions in impeller are analyzed in order to study the influences of vane diffuser and vaneless diffuser on flow field of a centrifugal compressor.
