ABSTRACT
Nonlinear effects associated with intense sound fields in fluids, are investigated theoretically. The analysis is based on the fundamental equations of motion for a thermoviscous fluid, for which thermal equations of state exist. Model equations are derived and used to analyze nonlinear sources for generation of mean motions. Special attention is focused on the importance of inhomogeneous waves as a source for generation of mean flow motions. Waves of this type can be propagated in the vicinity of the sound source and surface (interface) bounding the fluid.
