Abstract : The mechanism by which wall jets prevent boundary layer separation and diffuser stall has been experimentally examined. Mean velocity profiles and turbulence statistics in both the separated and jet-energized boundary layer have been measured in the presence of a coflowing stream and adverse pressure gradients. Some preliminary conclusions are suggested. (Author)
