摘要
利用智能型热线风速仪 ,采用单直丝和单斜丝联合多方位旋转采样技术[1 ] ,在 7种宽度下对离心压缩机无叶扩压器内部流场进行了测量。分别从时均速度、紊动能、气流角、静压恢复系数、总压损失系数等 5个方面进行了分析 ,从而得出了对工程应用和试验研究有着重要指导意义的结论。
Using intelligent hot line anemometer, single & monoclinal wire omnidirectional rotating sampling technique, measurement should be carried out to the internal flow field of centrifugal compressor vaneless diffuser under the seven kinds of width. Analysis is carried out in five respects. Then, the conclusion which has important guiding significance to engineering application & test research is obtained.
