摘要
对某离心压缩机改造前后的叶轮进行了数值分析。结果表明,改造前后叶轮均满足设计要求,但由于原始叶轮在入口处的相对马赫数较大,所引起的摩擦损失也略大,因此改造后的叶轮性能要好于改造前的叶轮,
The numerical method was employed to analyze centrifugal compressor impellers and those renovated. The analytical result indicates that the upgraded impeller outperforms the original one whose relative maeh number is high.
