Lectures on the Theory of Vortex-Sound

  • Michael S. Howe
Part of the Lecture Notes in Physics book series (LNP, volume 586)

Abstract

The theory of vortex sound is introduced. From Lighthill’s acoustic analogy, it is shown how vorticity and entropy fluctuations can be seen as sources of sound. The use of the compact Green’s functions is introduced to compute the vortex sound. As an example of the method presented, this theory is applied to pressure transients generated by high-speed trains.
