Experimental research on wall pressure distribution in C-D nozzle at Mach number 1.1 for area ratio 3.24

In this experimental investigation, the work reported is about the influence of control on the flow field in the suddenly expanded duct at low supersonic Mach number. A Convergent-divergent (CD) nozzle was designed and fabricated out of brass material assembled with the suddenly expanded duct which...
