Free-streamline (cavitating) flows in which the cavity size is a function of time. The cavity sur-face is a boundary surface, but not necessarily a stream surface. Cavities trailing a body entering a water surface are characteristic of nonstationary cavities.
The process of formation of nuclei in liquid. Also, sometimes used to refer to the process of stabilisation of nuclei to account for their persistence in undersaturated and saturated liquids.
Small bubbles, often sub-microscopic in size, containing permanent gas and/or the vapour of the liquid, which are required for inception of cavitation at the pressure near vapour pressure.
