In a Scramjet combustor, since the flow is supersonic, the residence time available is of the order of 1 millisecond. So the available time for fuel-air mixing, atomization, vaporization and combustion is very low. Wall mounted cavity has proven to be a capable candidate for fuel air mixing and flame stabilization for scramjet. Because of inherent advantages like symmetric flow, avoidance of base wall cooling, symmetric fuelling feasibility etc exploration of strut-mounted ‘through cavity’ has been done. It is a novel configuration formed in the space between two struts immersed in a supersonic flow in tandem. . Two variants of the cavity, formed by using rectangular and ramp strut as the rear strut and plug nozzle acts as the forward strut, have been used. Experimental characterization is carried out by unsteady pressure measurement inside the cavity for different aspect ratios.
