Supersonic Diffuser Research.
Abstract
The research concerned a survey of existing literature on supersonic diffusers, and experimental study on pressure recovery of supersonic diffusers in a variety of facilities with a variety of configurations following a contoured Mach Number = 3 nozzle. The nozzle and test section were free of models and the diffusers were either of constant cross section (straight duct), or of variable cross section, and they were generally patterned to be representative of some classes of gasdynamic laser nozzles. The optimum pressure recovery of the operating facility and the minimum pressure recovery required to start supersonic flow at the nozzle end were determined. The facilities used were a small continuous operation supersonic wind tunnel and a Ludwieg tube operating as a blow down wind tunnel with a steady state in the millisecond region. Careful correlation with data from other facilities taken under different circumstances was performed, while a number of the results found were unique to the current investigation.
