内容記述 | In this study, the bow-shock shape has been studied in front of finite length semi-circular convex, concave cylindrical arc and flat plate at hypersonic Mach number 7. The experiments were carried out in hypersonic wind tunnel for drag coefficient measurement and shock visualization using Schlieren method. Further, numerical simulations were performed for the finite length concave, convex and flat plate geometries by solving three-dimensional Navier-Strokes equations for wind tunnel test-section conditions. The effect of curvature on shock envelope and drag coefficient for these three geometries is studied. It is also observed that the same reference area of concave arc can produce instabilities in shock wave, which can lead to starting problem of tunnel. Hence, the Schlieren images were captured using highspeed camera with 5000 fps. The different patterns of shock instabilities have been observed in case of concave shape cylindrical arc. Among the different instability patterns, particle induced instability pattern has been studied by numerical simulation by using static particle located upstream of concave geometry in hypersonic flow simulation. | |||||
