Cavitation is usually divided into two classes of behavior. Inertial (or transient) cavitation is the process in which a void or bubble in a liquid rapidly collapses, producing a shock wave. It occurs in nature in the strikes of mantis shrimp and pistol shrimp, as well as in the vascular tissues of plants.
Cavitation is a process in early embryonic development that follows cleavage. Cavitation is the formation of the blastocoel , a fluid-filled cavity that defines the blastula , or in mammals the blastocyst . [ 1 ]
In a hydraulic circuit, net positive suction head (NPSH) may refer to one of two quantities in the analysis of cavitation: The Available NPSH (NPSH A): a measure of how close the fluid at a given point is to flashing, and so to cavitation. Technically it is the absolute pressure head minus the vapour pressure of the liquid.
Supercavitation is the use of a cavitation bubble to reduce skin friction drag on a submerged object and enable high speeds. Applications include torpedoes and propellers , but in theory, the technique could be extended to an entire underwater vessel.
The argument has been made that sonoluminescence releases too large an amount of energy and releases the energy on too short a time scale to be consistent with the vacuum energy explanation, [19] although other credible sources argue the vacuum energy explanation might yet prove to be correct. [20]
There were several hypotheses to explain the cracking of joints. Synovial fluid cavitation has some evidence to support it. [9] When a spinal manipulation is performed, the applied force separates the articular surfaces of a fully encapsulated synovial joint, which in turn creates a reduction in pressure within the joint cavity.
Cavitations are an area of dead or dying bone.They are caused by infections, physical trauma, or a dearth of blood flow to that part of the bone. [1]There is little evidence to support the theory of cavitation in the jawbone, and their diagnosis is highly controversial. [2]
The Rayleigh–Plesset equation is often applied to the study of cavitation bubbles, shown here forming behind a propeller.. In fluid mechanics, the Rayleigh–Plesset equation or Besant–Rayleigh–Plesset equation is a nonlinear ordinary differential equation which governs the dynamics of a spherical bubble in an infinite body of incompressible fluid.
