Numerical analysis of the energy efficiency of processes under the action of ultrasonic oscillations in systems with a continuous liquid phase for optimum control of the radiator operating

Abstract

The numerical analysis of the energy efficiency of processes in systems with a continuous liquid phase under the action of ultrasonic vibrations was performed. The analysis is aimed at determining the real ratio between the energy of changing the interatomic and intermolecular bonds of the medium and the total input energy of ultrasonic action. The performed analysis on the examples of the processes of mechanical destruction of macromolecules and dispersion evaluated dependences of the real energy consumption for the change of the interatomic and intermolecular bonds of the medium on vibrations intensity. The revealed dependences do not contradict the experimental data. The proposed modification of the previously created intensity control algorithm allows to increase the efficiency of ultrasonic exposure by 1.25…1.7 times according to calculations.

Calculation of optimal intensity of ultrasonic vibrations for removal of oxide films from the surface of ore pulp particles

“…10 8 Pa, the temperature of the vapor-gas mixture of the bubble increases to 6000 K, and the walls of the bubbles move towards each other with a velocity of 250÷340 m/sec. Shock waves are formed [21,22].…”

“…To achieve the destruction of ore pulp particles, it is necessary that the pressure generated by ultrasonic vibrations exceeds the limit of their tensile strength [22,23], i. e.:…”
