CAVITATION-TYPE HEAT GENERATOR Russian patent published in 2003 - IPC

FIELD: thermal engineering. SUBSTANCE: heat generator built around swirl injector actuated by booster pump may be used as mixer, homogenizer, disperser in various processes. At least one resonator made in the form of axisymmetrical chamber is mounted at nozzle exit of swirl injector and other axisymmetrical resonator communicating with injector space through central bore is installed at butt-end of swirl chamber in opposition to its nozzle. At least one resonator is designed as adjustablefrequency device and electrodes communicating with electric current supply are arranged in opposing end walls of resonators along their axes. Provision is made to control proportion of currents supplied to booster pump and to electrodes. EFFECT: enhanced efficiency, optimized heattransfer process. 4 cl, 3 dwg
