FIELD: power industry. ^ SUBSTANCE: heat generation method involves formation of primary flow of fluid working medium, bringing of primary flow into translational movement, superimposition of disturbing actions on flow, formation of secondary flows and discharge of working medium flow; at that, primary flow has characteristics of laminar streamline flow; then, flow is brought into translational-rotational movement with the specified speed. Translational flow movement is created in direction of longitudinal axis of heat generator, and rotational movement is created along helical line; at the same time, flow is compressed till the speed providing cavitation phenomena is obtained. Secondary cavitation flows are converted till stationary waves are obtained in them. Fluid working medium is saturated with gas before it is supplied to the process (e.g. with nitrogen) till saturation degree of 90-100% is achieved. Gas microbubbles are formation centres of cavitation cavities at closing of which considerable quantity of heat is released. ^ EFFECT: increasing the efficiency of heat generation process. |
