Abstract: The paper is concerned with measurements of 3D flow field at exit of the Blade Cascade SE1050. Data was collected using traversing device with a small five-hole conical probe. Prior to measurements of the flow exiting the blade cascade, investigations of inlet velocity profile and inlet turbulence intensity were conducted. Measurements of exit flow field were performed at design angle of incidence and at a transonic and a subsonic regime. Data analysis reveals development of distinctive vortex structures resulting from non-uniform inlet velocity profile. Origin of these structures results in increased loss of kinetic energy and spanwise shift of kinetic energy loss coefficient distribution.
