Modeling Turbulence-Induced Noise with Application to Noise Control.

Abstract

More recently, following cessation of effort concerned with development of a nonlinear dynamical model of wall turbulence, recent research was directed to topics related to fluid/structure interactions. A topic of considerable interest has been the production of low-wavenumber pressure and sound radiation by deformation of a compliant surface bounding a turbulent flow, operating via the nonlinear convolving of the turbulent wall pressure and response at convective wave-numbers. Some results have also been obtained regarding certain classical and prosaic model acoustic problems that are nevertheless useful in self-noise analyses.
