TWO-PHASE FLOW IN A PLANT FOR PRODUCTION OF CAVITATION DIAMONDS

Consideration is given to the regimes of water fl ow in a hydrodynamic-fl ow plant with cavitation and hydraulic shock. Calculations are carried out by the CFX hydrodynamic unit of the general physical computational system ANSYS and are compared with experimentally measured values of pressure; fl ow velocities are also computed. It is shown that the hydraulic shock ensures a growth of the order of 5 atm in the external pressure on a vapor bubble. The possibility of the nanodiamond forming in fl ows of carbon-containing fl uids in such regimes is discussed.
