Effect on base pressure in suddenly expanded flows with variable location of microjets

This paper presents results of an experimental investigation to study the effectiveness of micro jets to control the base pressure in suddenly expanded axi-symmetric ducts when the micro jets are placed at different location (i.e. at the base, at the duct, and at base as well as at the duct). The...
