In the present world, passive control finds application in various areas like flow over blunt
projectiles, missiles, supersonic parallel diffusers (for cruise correction), the engine of jets …

The Aerodynamic base drag because of negative pressure at the backward-facing step is a
general obstacle connected with all the moving projectiles. The aerodynamic base drag is …

This present study discusses the outcome of the experimental investigations, and the
efficacy of the tiny jets used to regulate the base pressure as well as the wall pressure in …

The drag force is an essential factor in any projectile, from road vehicles to rocket or aircraft.
The total drag includes skin friction drag, wave drag, and base drag. The base drag is the …

This article reports the outcome of the windtunnel investigation on the role of micro jets as an
active control on the wall pressure distribution. Four tiny jets of 1 mm diameter located at 90 …

This article investigates the wall pressure dissemination on a circular duct when the flow is
exhausted into a CD nozzle. This study aims at to scrutinize the static pressure on the duct …

The presence of a blunt base can be found in automobile industries as well as in the
aerospace industry. The blunt base caused the lower base pressure than ambient pressure …

This paper presents an experimental study of suddenly expanded flows at supersonic speed
is performed. A Convergent-divergent (CD) nozzle is used with suddenly expanded duct. At …

Although the demand for rockets and missiles has increased exponentially but the problems
of the gas dynamics related to these vehicles remains to be a challenge. The main problem …
