Introduction to Cavitation and Supercavitation.

摘要

Cavitation, i.e. the appearance of vapor bubbles and pockets inside an initially homogeneous liquid medium, occurs in very different situations. According to the flow configuration (shape and relative motion of the walls limiting the flow field, or physical properties of the liquid), it can take various figures. In order to encompass all possible cases, we propose the following definition Cavitation is the breaking of a liquid medium under excessive stresses. That definition makes cavitation relevant to the field and the methods of continuum mechanics. It is convenient for cases in which the liquid is either still or flowing.
