摘要：
A computational investigation has been conducted to determine the effectiveness of a passive control technique ofattenuating cavity-induced pressure oscillations in a confined two-dimensional supersonic flow.The passivecontrol technique is achieved by fitting two flat plates near the front wall of a square cavity at Mach number 1.83at the cavity entrance.The results showed that the flat plates attached near the front wall of the cavity,discouraged the formation of feedback loop which is widely believed to be the reason of cavity resonance.Theresultant amount of attenuation of pressure oscillations was also dependent on the length of the fiat plate used asan oscillation suppressor.
