An Experimental Study on Mixing Characteristics of Supersonic Rectangular Coflow Jets of Different Aspect Ratio

Abstract

Experimental investigation of jets is an active research field for the past few decades because of the wide-ranging applications of jets. Jet flow finds much application in the field of engineering in automotive, aircraft gas turbine engines, rocket engines, and fuel-oxidizer mixing in the combustion chamber. It is much needed to understand the aerodynamic and aero acoustic features of subsonic and supersonic jets before employing them for practical applications. newlineThe progress of jet stream may be varied in terms of aspect ratio (AR), nozzle exit geometry, initial induced turbulence level, and flow Reynolds number. Circular nozzles are predominantly used in many engineering devices, but non-circular nozzles are preferred primarily due to their desirable mixing characteristics newline
