DYNAMICS OF A TRANSLATIONING CAVITY IN A LIQUID,
Abstract
A strong sound field in a liquid may generate small cavities that move rapidly through the liquid. The study is an analysis of the dynamics of a cavity in translational motion. A principal conclusion is that translating cavities have a stable size and shape for a wide range of conditions. It is also found that the presence of translational motion contributes an outward dynamic pressure that tends to enlarge the cavity. As a result, the equilibrium radius of a translating cavity is greater than the equilibrium radius of the same cavity at rest. The analysis is divided into two parts. The first part is a study of the equilibrium size and shape, stability, and modes of oscillation of a translating cavity in an infinite, incompressible and inviscid liquid. In the second part an approximate model is introduced in order to study the radial motion without the complexities due to the time dependence of the cavity shape. (Author)
