Emerging Computational Tools for Flow Acoustics

Abstract

This lecture is a survey of multiple on-going efforts in the United States, largely sponsored by the Office Of Naval Research, that are devoted to the development of prediction methods for flow-generated sound. This research is meant to develop methods that are useful in future engineering applications that could involve complex three-dimensional geometries, high Reynolds number fluid mechanics, flow-induced vibration, and finite Mach number. This paper will focus specifically on development of tools for the calculation of forcing functions and on efforts to systematically validate them in anechoic wind tunnels. The slides that are discussed herein form a complete description of work as currently undertaken at the David Taylor Model Basin of NSWC-CD and its collegiate organizations.
