Pressure Recovery in Rectangular Adjustable Area Supersonic Diffusers.

Abstract

Following an investigation of a simple, rectangular constant area duct supersonic diffuser, three types of variable area diffusers have been tested. Again these diffusers consisted essentially of a duct, but with two opposing pivoting elements to form a second throat smaller than the nozzle exit area. As expected, the performance of a refined diffuser can be better than that of a simple duct.
