Abstract : An experimental investigation was made of the general behavior of an air jet impinging obliquely on a circular flat plate. Surface pressure distributions and velocity profiles of the resulting wall jet were measured. Typical stagnation point radial velocity gradients, their dependence on impingement angle, and their correlation with local free jet properties were also determined. Throughout the range of impingement angles studied the wall jet thickness was found to be relatively constant around the plate perimeter. The azimuthal variation of momentum flux per radian depended strongly on impingement angle and only slightly on jet strength and impingement distance.
