Theory of Vortex Sound M. S. Howe

The book is an introduction to the branch of fluid mechanics concerned with the production of sound by hydrodynamic flows. It is designed for a one semester introductory course at advanced undergraduate or graduate level. Great care is taken to explain underlying fluid mechanical and acoustic concepts, and to describe as fully as possible the steps in a complicated derivation. The discussion deals specifically with low Mach number flows, which enables the sound produced by ‘vortex-surface’ interactions to be analysed using the ‘compact Green’s function’. This provides a routine procedure for estimating the sound, and an easy identification of those parts of a structure that are likely to be important sources of sound. Each chapter ends with a set of problems, many of which can form the basis of an extended student project. The final chapter contains worked examples that have been investigated by students at Boston University.

In The Press

The worked out examples in this book are of considerable practical importance to those working in the field of hydrodynamically generated sound. Thus, one can use the solutions directly without necessarily understanding all of the details of the derivation to solve practical problems of engineering interest. … The book meets the objectives set down by the author completely. I recommend it without reservation to those working in the complex field of flow-induced noise.’ Journal of Sound and Vibration
