Physics of prestall propagating disturbances in axial compressors and their potential as a stall warning indicator

Eck, Mario ; Geist, Silvio ; Peitsch, Dieter (2017)

Axial compressors in aero engines are prone to suffering a breakdown of orderly flow when operating at the peak of the pressure rise characteristic. The damaging potential of separated flows is why a safe distance has to be left between every possible operating point and an operating point at which stall occurs. During earlier investigations of stall inception mechanisms, a new type of prestall...
