Optimizing design method for centrifugal impeller its engineering application and numerical simulation
-
摘要: 介绍了一种离心叶轮的优化设计方法,该设计方法被应用到了一台离心压气机的具体工程设计.三维粘性计算流体软件被用来对所设计的离心叶轮进行了数值模拟.压气机的试验结果和数值模拟的结果从两个不同的侧面对该优化设计方法做出了客观的评估.Abstract: An optimizing design method for centrifugal compressor impeller has been presented, which has been applied to an engineering design of a practical centrifugal compressor. 3D viscous numerical simulation has been performed to these three stage compressors with CFD software TASCflow. Therefore the optimizing design method has been evaluated objectively by experiment data and numerical simulation results.
