Wavy Shaped Cylindrical Geometries for Aero-thermal Signature Alteration
Wavy cylindrical exhaust geometries condition aero-thermal flow to alter acoustic/thermal signatures and enhance mixing or cooling in propulsion systems.
Researchers at Purdue University have developed wavy-shaped geometries for use in subsonic, transonic, and supersonic exhaust flows to condition the aero-thermal flow properties. This invention can be tailored to produce targeted heat transfer distributions, enhance flow mixing, or abate the acoustic signature. This technology has applications in the design of gas turbines or propulsion systems
Advantages
