Aerodynamic Noise

This book covers the theoretical basis and mathematical modeling of sound, especially undesirable sounds produced by aircraft, such as engine noise from propellers, fans, combustion chamber and jets, external surface noise and sonic booms. Offers problem sets.

Aerodynamic Noise extensively covers the theoretical basis and mathematical modeling of sound, especially the undesirable sounds produced by aircraft. This noise could come from an aircraft's enginepropellers, fans, combustion chamber, jetsor the vehicle itselfexternal surfacesor from sonic booms. The majority of the sound produced is due to the motion of air and its interaction with solid boundaries, and this is the main discussion of the book. With problem sets at the end of each chapter, Aerodynamic Noise is ideal for graduate students of mechanical and aerospace engineering. It may also be useful for designers of cars, trains, and wind turbines.

Features the latest information about the theory of aerodynamic noise and numerical procedures for Computational Aeroacoustics (CAA) Covers the issue of noise at and around airports in addition to aircraft noise Includes exercises at the end of each chapter

Autorentext

Tarit Bose is a retired professor of aerospace engineering from the Indian Institute of Technology Madras (IIT-M), India. He retired in 1998 after 27 years of teaching "Thermodynamics", "Aircraft Propulsion", "CFD and Plasma Dynamics". During his time at IIT-M; Tarit supervised 16 masters level candidates and 10 doctoral candidates.

Tarit received his Diploma in Mechanical Engineering from the University of Munich, West Germany in 1960. He received his Doctorate in Aerospace Engineering from the University of Stuttgart, West Germany in 1965. Tarit worked for NASA-NRC as a resident research associate in the heat transfer group, propulsion research and advanced concepts section of Jet Propulsion Laboratory (JPL), Pasadena from June 1968 through May 1970. Prior to JPL Tarit was a research fellow at the University of Minnesota heat transfer laboratory.

In 1998 Tarit joined Metacomp Technologies, Agoura Hills, CA as a research scientist. He has since retired and is pursuing personal projects.
