Aeroacoustics of Low Mach Number Flows: Fundamentals, Analysis and Measurement

Aeroacoustics of Low Mach Number Flows: Fundamentals, Analysis and Measurementprovides a comprehensive treatment of sound radiation from subsonic flow over moving surfaces, which is the most widespread cause of flow noise in engineering systems. This includes fan noise, rotor noise, wind turbine noise, boundary layer noise, airframe noise, and aircraft noise. The basic equations of aeroacoustics are derived so that they apply to both subsonic and transonic flows. The authors cover the essential theory behind hydro and aeroacoustics before explaining the numerical methods used in analyzing low mach number flows and the scenarios where they are used. This is the definitive guide to hydro and aerodynamics, and is perfect for all graduate students and engineers interested in the subject. Addresses sound from rotating blades, ducted fans, airframes, boundary layers, and moreCrucially updates the literature on hydro and aeroacoustics by exploring the use of the Ffowcs Williams and Hawkings equationsPresents theory in such a way that it can be used in computational methods and in calculating sound levelsIncludes coverage of different experimental approaches to this subject INDICE: Part 1: Fundamentals 1.
