On the Interaction of Intense Acoustic Fields and Viscous Fluid Flows

Abstract

A survey is given of several analytical techniques that can be applied to acoustic streaming phenomena. A method is selected for examining intense acoustic field-viscous fluid flow interaction problems in which the flow oscillation magnitude is much larger than any time-mean flow component. The method itself has a wide range of applicability and provides a clear and explicit statement of the approximations involved. The major goal of the paper is to illustrate this method by applying it to a new problem; namely, the interaction of an intense transverse resonant acoustic field with simple channel flow. The solution, while simple, possesses some very interesting heat transfer aspects.
