Jet noise remains a significant noise component in modern aero-engines. A high-speed flow mixing with the surrounding air constitutes noise sources behind the nozzle. This book consists of two parts. The first part is to provide an overview of the aircraft noise generating sources with emphasis on the jet noise, the main technologies employed for control and reduction of aircraft noise for subsonic and supersonic jets, and finally a survey of the current applications of large-eddy simulation (LES) for predicting of the noise from single stream turbulent jets, including numerical methods for…mehr

Produktbeschreibung
Jet noise remains a significant noise component in modern aero-engines. A high-speed flow mixing with the surrounding air constitutes noise sources behind the nozzle. This book consists of two parts. The first part is to provide an overview of the aircraft noise generating sources with emphasis on the jet noise, the main technologies employed for control and reduction of aircraft noise for subsonic and supersonic jets, and finally a survey of the current applications of large-eddy simulation (LES) for predicting of the noise from single stream turbulent jets, including numerical methods for simulation of near and far field of a jet nozzle. The second part of the book describes a test rig constructed for the study of jet noise from JetCat micro turbojet engine used for unmanned aerial vehicles (UAV) to investigate the near field noise generated by turbulent high subsonic single stream jet.
