ABSTRACT	Ring patterns of oil deposition on the front surface of an Orbital Re-Entry Experiment vehicle (OREX) model were observed in supersonic wind tunnel experiments of oil flow visualization. To investigate the cause of this phenomenon, oil flow visualization on areases or to increases downstream. Thus, the ring patterns are laminar boundary layer bubbles on the OREX model caused by unfavorable pressure gradients
