Experimental studies on low speed converging nozzle flow with sudden expansion

Experimental studies on low speed converging nozzle flow with sudden expansion

This paper presents the results of experimental studies conducted to study the base pressure field from a convergent nozzle to ascertain the effect of micro jets, the length to diameter ratio, Mach number and area ratio in a suddenly expanded flow. The Mach numbers of the present study are 0.2, 0.4,...
