1. The sudden formation and collapse of low-pressure bubbles in liquids by means of mechanical forces, such as those resulting from rotation of a marine propeller.
2. The pitting of a solid surface.
3. Medicine The formation of cavities in a body tissue or an organ, especially those formed in the lung as a result of tuberculosis.

[From cavity.]

Trim the engine/outdrive up and the bow rises--too much, and the hull can porpoise and the props aerate or cavitate.
In practice, these are difficult to differentiate on CT, having in common well-marginated solitary or multiple pulmonary nodules/masses that can cavitate and calcify.
Squamous cell carcinoma of the lung is the histologic type most likely to cavitate, and one might wonder if that is because the squamous type is more likely to invade blood vessels, cut off blood supply, and cause ischemic necrosis.
The lack of fluid had caused the hydraulic pump to cavitate, overheat and catch fire, which forced an emergency landing in Iraq.
The microspheres, developed by ImaRx Therapeutics, are tiny gas-filled lipid structures that cavitate (rapidly expand and collapse) when exposed to ultrasound waves, helping to reopen blocked arteries and restore blood flow.
In order to understand the pressure build development in the case of orbital motion, it should be noted that kinematic (Please refer Appendix A for the kinematic analysis of the orbiting thrust bearings) position analysis shows that the locus of an arbitrary control volume centroid P on the orbiting disk shown in Figure 1 is a circle of radius, equal to eccentricity (e) of the crankshaft driving the plate, hence during a part of rotation of crankshaft point P moves out of pocket experiencing a converging wedge and giving rise to pressure spike at the edge of the pocket and during remaining part it experiences a diverging wedge causing the fluid to cavitate.
This tendency for large diameter elements to cavitate and embolize more readily than small diameter ones has also been noted by other experimenters (Tyree & Dixon, 1986; Dixon et al.
In the presence of ultrasound, the microbubbles cavitate (expand and collapse), releasing energy that may potentially dissolve the blood clot.
Also, when chips, fines, and super fines accumulate in the reservoir - to the point where their volume displaces too much of the fluid - pumps cavitate, and the coolant temperature elevates, resulting in evaporating and possible issues detrimental to part quality.
Uvivid does not foam or cavitate in the ink pan, and ensures optimal ink transfer from the anilox rolls, according to Sericol.
Patients, especially the immunosuppressed, may have bilateral nodular opacities that may expand and cavitate (12).
