Theory of Vortex Sound (Cambridge Texts in Applied Mathematics, Series Number 33)

Publisher Description (unedited publisher data) 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 "Theory of Vortex Sound is an introduction to the theory of sound generated by hydrodynamic flows. Starting with a review of elementary theoretical acoustics, the book proceeds to a unified treatment of low Mach number vortex-surface interaction noise in terms of the compact Green's function. Problems are provided at the end of each chapter, many of which can be used for extended student projects, and a whole chapter is devoted to worked examples." "It is designed for a one-semester introductory course at the advanced undergraduate or graduate levels.

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. The book is an introduction to theory of sound generation by fluid flow, specially written for a one semester course at advanced undergraduate or graduate level. Problems are provided at the end of each chapter, many of which can be used for extended student projects. A whole chapter is devoted to worked examples. Vortex sound is the sound produced as a by-product of unsteady fluid motions (Fig. 1.1.1).
