High-speed jet noise

Abstract

Aeronautical and space applications, but more generally various engineering issues, are concerned with noise of high-speed jets. This comprehensive review provides a summary of noise generated by supersonic round jets, including mixing noise, Mach wave radiation, broadband shock-cell noise and screech tones, examines efforts to understand the physics involved, and introduces recent numerical and experimental developments regarding high speed jet noise. It outlines also aerospace applications with topics such as rocket supersonic jet impinging a flame deflector installed on launch pads.
