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.

通过建立EFD/CFD混合分析方法，将分离涡流模拟(DES)得到的CFD(计算流体动力学)结果和壁面压力非定常测量得到的EFD(实验流体动力学)结果相结合，发展了一种三维内部流动现象的诊断技术。目前的流动诊断技术已经阐明了跨音速离心式压气机旋转失速和叶尖泄漏涡破裂的现象，轴流压气机转子旋转失速起始的流动机理，以及半导管螺旋桨风扇的非定常涡流现象。
