The kinetic energy loss and the secondary loss downstream of a high turning nozzle cascade were investigated. Influence of the incidence angle (i= -25 degrees, 0 degrees and 25 degrees) and Reynolds number (Re-2,Re-is =0.8x10(5), 1.2x10(5), 2.5x10(5) and 4.5x10(5)) were studied on two cascade configurations defined by different pitch to chord ratio (t/c=0.6 and 0.9), respectively. Measurements at the cascade inlet were performed by means of Preston tube, while at the cascade outlet by means of miniature pyramid five-hole pressure probe. An effect of studied parameters on the flow field at the cascade outlet was shown by the distribution of the kinetic energy loss, secondary loss, mix-out loss and streamwise vorticity.
