Simulations of supersonic turbulent flow over an open rectangular cavity are performed to observe the effects of length to depth ratio (L/D) of the cavity on the flow structure. Two-dimensional compressible time-dependent Reynolds-averaged Navier-Stokes equations with k-ω turbulence model are solved. A reduced order modeling approach, Proper Orthogonal Decomposition (POD) method, is used to fur...

Control surface deployment in a supersonic flow has many applications, including control, mixing, and body-force regulation. The extent of control deflections introduces varying unsteadiness. resulting fluid dynamics influence the downstream characteristics fluid–structure interactions significantly. In order to understand gas dynamics, an axisymmetric cylindrical body with sharp-tip cone at ze...
