Cavitation

Cavitation is a phenomenon in which rapid changes of pressure in a liquid lead to the formation of small vapor-filled cavities, in places where the pressure is relatively low. When subjected to higher pressure, these cavities, called “bubbles” or “voids”, collapse and can generate an intense shock wave Cavitation is a significant cause of wear in…

Fluid

In , a fluid is a substance that continually deforms (flows) under an applied  shear stress, or external force. Fluids are a phase of matter and include liquids, gases and plasmas. They are substances with zero shear modulus, or, in simpler terms, substances which cannot resist any shear force applied to them. Although the term “fluid” includes both…
