摘要
基于离心压气机的设计需求,利用流线曲率法对某型离心压气机进行通流计算,加入几种常用的离心叶轮损失模型,验证计算方法的正确性。重点研究通流计算中选取的几种损失模型对于计算结果的影响,并经过对比分析,得出研究结果。
Based on the requirements of the centrifugal compressor design, this paper has carried out centrif- ugal compressor through-flow calculation by using the streamline curvature method with several common loss models. Firstly, the through-flow code with loss model is verified. Then it investigates different loss model effects on centrifugal compressor performance. The results show that the loss models have a great effect on centrifugal compressor impeller efficiency, and the tip clearance loss is dominant while wake loss is comparative smaller among all the loss models.
