Two flat turbine cascades have been experimentally investigated in a wide range of the reduced isentropic velocity and the Reynolds number under various turbulent parameters of a flow at the cascades’ inlet generated by means of grids. Turbulence parameters were measured using a hot-wire anemometer and a high-frequency pressure probe.
