A passive boundary-layer control, which consists of porous wall with cavity, may be the useful technique for alleviation of shock oscillations. In order to clarify the effect of the control on flow patterns around a cylindrical protuberance in the supersonic flow, flow visualizations have been carried out using the vapor-screen method.The flow patterns have been shown especially for the three-dimensional shock configurations, and compared with those for solid wall. Results indicate that there appears the distinct difference in shock structures.
