Steady and unsteady cascade measurements

Velocity and turbulence intensity measurements were made in a linear stationary cascade of compressor blades under high angles of attack. Laser-doppler velocimetry and flow visualization were used. A method was developed for inducing propagating stall and some triggered ensemble averaged velocity re...
