The impinging shock of varying strengths on the free shear layer in a confined supersonic cavity flow is studied numerically using detached eddy simulation. resulting spatiotemporal variations are analyzed between different cases unsteady statistics, x–t diagrams, spectral analysis, and modal decomposition. A length to depth ratio [ L / D ] = 2 at freestream Mach number M ? 1.71 considered be p...

Abstract This work analyses the isothermal flow field of a research burner exploiting both swirl and radially staged combustion air. The is composed two coaxial co-rotating swirling jets, level jets can be controlled independently each other. influence levels on experimentally investigated under conditions using Stereo-PIV technique, results evidence significant differences in mean at different...
