Cooling of the inner-chamber elements of a thermonuclear reactor with a dispersed flow

Abstract

A method of temperature stabilization of the limiter of the Tokamak T-10 with capillary-porous structure on the side facing the plasma and saturated with liquid lithium, by dispersed gas-liquid flow is considered. The spray pattern, formed by the spray generator, is directed along the axis of the divertor. The results of experiments for determining the geometric characteristics of a torch, a dispersed flow, the distribution of the velocity and the size of water droplets in dependence on the pressure of water and air entering the generator nozzle are presented. The technique developed by the authors for processing experimental data is presented, which makes it possible to calculate the density of the heat flux, the temperature on the outer (heated) and internal (cooled) surface of the target walls. The design of the working area-divertor simulator is developed. It was experimentally established that the temperature of the target sharply decreased when air was supplied to the generator nozzle. The main experiments were carried out at excess water pressures (1.0 ÷ 3.5)•105 Pa, air (1.0 ÷ 4.0)•105 Pa, and heat flux densities of up to 8 MW/m2 applied to the target.
