An Inlet Flow Angle Effect on a Horse-Shoe Vortex Formation

Abstract

The static pressure distribution on the end-wall of a linear blade cascade for different inlet flow angles is investigated in this contribution. The experiments were performed for constant values of Reynolds number (Re2,is = 4.5 × 105) and Mach number (M2,is = 0.4). These data are presented in the form of static pressure gradients. The obtained quantitative results are supported by surface flow visualization.
