Abstract:
This report describes detailed heating distribution data and the study of oilflow and liquid crystal thermograph in turbulent separated regions induced by cylindrical,square and two-dimensional steps in an impusle wind tunnel at Mach number range of 5-9,Reynolds number(2-5)×10￣7/m,Step heights ranged from 0.06-2.5 times boundarylayer thickness. The results indicate that surface pressure and heating peaks occur at thereattachment line which is at a distance of 0.15 times its height ahead of the step,and for...
