| Research Abstract |
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.
