内容記述 | In the present study, features of oscillatory supersonic flows over a rectangular cavity are measured by changing the initial shear-layer property for the purpose of validating the numerical flow simulation performed as future work. In the experiments, two inlet flows having the same Mach number of 1.7 and different initial shear-layer properties are tested. The pressure oscillation is measured at the bottom wall of the cavity by use of the semiconductor-type pressure transducer by changing the length-to-depth ratio of the cavity at each condition. The instantaneous flow fields are also visualized by the schlieren method with a high-speed camera. As a result, it is found that the dominant oscillation frequency and the strength in pressure oscillation depend strongly not only on the length-to-depth ratio but also on the initial shear-layer property. | |||||
