Abstract : Experimental measurements in a separating turbulent boundary layer were made. Mean velocity and turbulence intensity profiles were obtained using hot film and laser anemometry. Mean and fluctuating wall shear stress distributions were obtained using flush mounted hot film sensors. The bursting frequency at various streamwise locations was also obtained from the wall hot film sensors. The intermittency was obtained utilizing a photo-electric technique. The celerities of various eddy structures were obtained by using a double hot film probe. (Modified author abstract)
