Read: What is Cavitation?

Advantages and application of cavitation

  • Cavitation found application in ultrasonic cleaning baths. It has sufficient force to overcome the adhesive force between molecules of impurity and clean surface.
  • Controlled cavitation phenomenon can be used to enhance a chemical reaction.
  • Cavitation process uses to homogenize and mix the suspended particles in colloidal liquids.
  • Cavitation used to improve the performance of high-speed marine vessels and projectiles.
  • Cavitation in wastewater treatment - extreme cavitation use to break down pollutants and organic molecules.
  • The field of material processing technologies and medicine use the advantages of cavitation.
  • In shock wave lithotripsy, cavitation plays major roles in the destruction of kidney stones. Cavitation also used in other medical treatments (eg: Liposuction), where ultrasound is used.

Disadvantages of Cavitation

  • Shockwave produced by collapsing of bubble cause significant damage in moving parts of hydraulic machines.
  • Cavitation causes vibration and noise.
  • Cyclic stress on boundary surface cause the fatigue of material.
  • Localized cavitation causes stress erosion of metallic surfaces and produce cavities in it.
  • The shock wave produced by cavitation is the one of the problems of military submarines, it exposes the position of submarine.
  • Cavitation in pumps, turbine and other hydraulic machines restricts the flow of fluid and reduce the efficiency.
