摘　　要：从压缩机模型级数据库中选型,得到压缩机基本几何参数,对轮盖型线和叶片型线重新进行设计。应用流动分析软件对该压缩机内部流场进行了模拟,性能预测结果表明能够满足燃料电池对压缩机的要求。The basic geometrical parameters of compressor were obtained by choosing a model from the compressor database. The shroud line and the blade profile were redesigned. Flow analysis software was adopted to simulate the internal flow of the compressor. The performance prediction results indicate that the centrifugal compressor designed in this paper meets the requirements of the fuel cell.
