The measurement of the flowfield at the peak pressure rise condition in an axial flow compressor rotor is reported in this paper. The inviscid flow measurements was carried out using a laser Doppler velocimeter and the blade boundary layers were measured using a two-sensor hot-wire probe. The blade-to-blade distribution of velocities at several and radial locations are plotted, interpreted and compared with the conditions existing at a lower (design) flow coefficient. The leading-edge effects of inviscid flow and found to be appreciable. The flowfield is dominated by inviscid flow at most radial locations and the blade boundary-layer thickness is found to be appreciable in the tip region. The flow near the tip is dominated by leakage and its influence is more severe at the peak pressure rise condition.
