Ultrasonics
Ultrasonics is a trade term used to refer to the use of high-intensity acoustic energy to clean materials. Ultrasonication offers great potential in the processing of liquids and slurries, by improving the mixing and chemicals reactions in various applications and industries. It generates alternating low-pressure and high-pressure waves in liquids, leading to the formation and violent collapse of small vaccum bubbles. This phenomenon is termed cavitation and causes high speed impinging liquid jets and strong hydrodynamic shear-forces.
