Aerodynamic Noise An Introduction for Physicists and Engineers [Paperback]

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 aircrafts 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.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.
