Analysis of parameters affecting thrust and base pressure in suddenly expanded flow from nozzle

In the case of flow from the nozzle, the net thrust is the vital and critical consideration. The net thrust force is the difference of the thrust developed by the jet from the nozzle and the base drag. The pressure in the base area of a duct with the sudden expansion usually is lower than the ambien...
