Název v původním jazyce

Cavitation Disintegration of Powder Microparticles

Popis výsledku v původním jazyce

The chapter studies the potential of cavitation not only as a standard procedure of deagglomeration of coagulating dispersions, but also as the perspective tool of direct disintegration of compact particles. It includes an introduction to the theory of cavitation dynamics and the discussion of basic mechanisms taking part in the disintegration of large and small particles in this way. A new instrument of extreme nanogrinding based on a high-pressure liquid jet (Water Jet Mill - WJM) is also introduced and the principles of its operation including velocity gradient due to shear forces, the water hammer effect during cavitation implosions and the direct impact of particles at a hard tungsten carbide target are discussed. The experiments with powerful sonification of very dense liquid dispersions of microparticles, as well as the tests of the WJM provide promising results with perspective application in disintegration of solids up to the nanoscale.
