cav·i·ta·tion

 (kăv′ĭ-tā′shən)
n.
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.]

cavitation

(ˌkævɪˈteɪʃən)
n
1. (General Physics) the formation of vapour- or gas-filled cavities in a flowing liquid when tensile stress is superimposed on the ambient pressure
2. the formation of cavities in a structure

cav•i•ta•tion

(ˌkæv ɪˈteɪ ʃən)

n.
1. the rapid formation and collapse of vapor pockets in a flowing liquid in regions of very low pressure, often causing structural damage to propellers, pumps, etc.
2. the formation of cavities, esp in a part of the body.

However, affected by the variable internal flow patterns and unstable cavitation structure and position [18], the sac pressure of the multi-hole nozzle has small waves under the two injection quantity conditions.
All of the unstable cavitation structure described above inside the multi-hole nozzle can be used to explain its unique and fickle spray behaviors observed in the experiment.
Compared with the simple-structure single-hole nozzle, the internal flow patterns inside the complex-geometry multi-hole nozzle are dominated by the lower sac pressure, vortex flow in the sac, and complex spiral flow structure inside the hole, which can generate fluctuated injection velocity, unstable cavitation structure, and higher turbulence kinetic energy gradient.
