Experimental investigation of the base flow from the nozzles with sudden expansion

This paper presents the outcome of the experimental investigation conducted to control the base pressure for suddenly expanded flow for a fairly high area ratio of non-dimensional backward facing step height of 2.2. The Mach number range of the study were from 1.25 to 3.0 and the NPRs in the range f...
