Abstract

The task of the scientific research is to estimate the energy intensity of the work of the developed supercavitational generator in comparison with the classical cavitation generator "Venturi tube". To solve the task at the scientific research the classical approach was used, which consists in comparing the pressure loss on the investigated cavitation generators. The main conclusions are as follows: the effectiveness of the use of hydrodynamic cavitation is confirmed by the development of methods and devices for the intensification of technological processes and the reduction of energy consumption in the mining industry; the design of the cavitation generator organically fits into various technologies and allows to intensify them at lower specific energy inputs, does not require labor-consuming modification of the equipment; the specific energy consumption in the supercavitation generator is less by 3-5 times than on the standard generator of the Venturi tube. As a criterion for the cavitation oscillators studied, the oscillation frequency was the oscillation frequency. Practical value consists in using a less energy-intensive cavitator in various technological processes when drilling wells. The originality and value of research lies in the development of completely new designs of cavitation generators and the rationale for their application in drilling wells in terms of energy intensity
