The flow characteristics of the turbine stage, which runs at a high pressure ratio, are complicated by the appearance of shock and expansion waves. An exact numerical method by which to calculate the influence of such unsteady phenomena is impossible due to interaction and reflection of shock waves effected by the boundary layer. Therefore, flow visualization of the entire stage cascade on running was made by the Schlieren method employing a stroboscope, and a flow analysis was executed on the basis of the photograph's color. In addition, the pressure fluctuation at the stationary blade exit point was measured. Detached shock waves created in front of the moving blades could verify the influence on the cascade flow.
