WitrynaA temporally resolved flow visualization system that produces 17 flow images over a time span of 128 microseconds is used to visualize the mixing layers of a Mach 1.28 (M c =0.59) and a Mach 2.06 (M c =0.87) ideally expanded high Reynolds number axisymmetric jets. These image sequences revealed details about the effects of … Witrynathe impinging jet scenario. The wall jet resulting from axisymmetric impinging jets has been studied experimentally [15, 16]; the studies show that the wall jet developed downstream of impingement does demonstrate self-similar behavior. We present a parametric study that characterizes the velocity profile and wall shear stress of the
