Passive control of sonic flow from converging nozzle with D-shaped rib

Results in Engineering
The abrupt expansion at the blunt base of projectiles, rockets, missiles, etc., is a common phenomenon. Flow separation and reattachment are caused by the abrupt increase in the base area, and the pressure in the separated recirculation area is lower ...
