Mixing Enhancement Using Propulsive Means
The invention is expected to impact the state of the art in many applications, including fuel injectors, reduction of thermal emissions from aircraft engines, jet noise suppression, supersonic combustion, materials processing, ejector pumps, and chemical lasers.
A novel mixing enhancement method exploits a previously unknown flow instability to enhance mixing in a compressible jet flow or in a flow (gaseous of liquid) in contact with the compressible jet flow. No mechanical mixers and no actuators of any kind are used. Nozzle shapes are streamlined and simple.

Title: Mixing enhancement using axial flow
Usefulness: Mixing enhancement using axial flow
Summary: For fuel injectors, sprays, chemical laser, for combustion, propulsion, fluid pumping, material processing, inside and outside exhaust duct of turbine engines.
Novelty: Fluid mixing enhancing method for fuel injectors, involves accelerating sub-sonic flow generated by flow generator near converging area, resulting in flow at exit area
