This paper examines the flow structures emanating from convergent-divergent nozzles with conical sections like those used in practical high-speed propulsion applications. LES simulations and experimental measurements in the form of PIV and shadowgraph imaging and far-field acoustic measurement are employed. The development of the supersonic jets from these(More)
Large-eddy simulations of imperfectly expanded jet flows from a convergent-divergent nozzle with a heated (600K) and a cold jet conditions have been carried out. Mach wave radiation is present outside the jet core and the heated jet shows a much larger density shear-layer spreading than the cold jet. The potential core length is shortened, but the(More)
