A diagnostic technique for three-dimensional internal flow phenomena has been developed by building a EFD/CFD hybrid analysis approach, in which CFD(Computational Fluid Dynamics) results obtained by DES(Detached Eddy Simulation) and EFD(Experimental Fluid Dynamics) results obtained by unsteady measurement of wall pressure have been combined. The present flow diagnostic technique has elucidated phenomena in the rotating stall and tip leakage vortex breakdown in transonic centrifugal compressors, flow mechanisms of the rotating stall inception in an axial flow compressor rotor, and unsteady vortical flow phenomena in a half-ducted propeller fan.

通过构建EFD/CFD混合分析方法，已经开发了针对三维内部流动现象的诊断技术，其中CFD（计算流体动力学）通过DES（DESEDEDEDED涡流模拟）和EFD（实验流体动力学）获得的结果通过不稳定的壁压测量获得的结果。目前的流量诊断技术已经阐明了旋转失速中的现象和跨性别离心压缩机中的尖端泄漏涡流分解，轴向流动压缩机转子中旋转失速的流动机制以及在半为导管的旋转流动转子中的不稳定流动流动现象。
