Abstract

A study was conducted to demonstrate the mixing enhancement in subsonic jet flow by using the air-tab technique. Mixing enhancement can play significant role in jet flow applications for aircraft propulsion and combustion. Mixing enhancement can also be used to suppress the infrared red signature for the fighter jet exhausts during military operations. The air-tab technique involve the injection a small amount of air into the plume of the primary jet at choked speed at a specified attacking angles. The air-tab technique can make minimum impact on thrust and significant impact on the mixing enhancement. It was observed during the study that the compressed air tapped from the compressor can reduce the amount of exhaust gas discharged from the nozzle. The study concluded that air-tab technique can effectively reduce the thrust during jet flow operation.
