In the liquid filled gap between two parallel plates, substantial negativ pressures can be generated, when the plates are separated with finite velocity. In untreated liquids, there are usually sufficient nuclei to give rise to cavitation bubbles, which will grow primarily by vaporisation from the cavity wall. The rate of growth will be limited by the reaction of the surrounding fluid, i.e. the inertial and/or frictional resistance of the fluid, and the ability of the liquid to provide, by conduction, the necessary heat of evaporisation to the bubble. For a bubble not in thermodynamic equilibrium (where the pressure in the bubble is not the saturation pressure at the temperature of the cavity wall) a rate equation will be required in addition to the effects mentioned.
