The paper considers a method of temperature stabilization of the limiter in the T-10 Tokamak with capillary-porous structure on the side facing of the plasma and saturated with liquid lithium, by dispersed gas-liquid flow. The spray pattern, formed by the spray generator, is directed along the axis of the limiter. The results of preliminary experiments for determining the geometric characteristics of a torch, a dispersed flow, the distribution of the velocity and the size of water droplets depending on the pressure of water and air entering the generator nozzle are presented. The paper presents the technique developed by the authors for processing experimental data, which makes it possible to calculate the heat flux density, as well as the temperature on the outer (heated) and internal (cooled) surface of the target walls. The design of the working area - limiter 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 (0.5 ÷ 1.0)·105 Pa, air (0.3 ÷ 2.8)·105 Pa, and heat flux densities of up to 4.9 MW/m2 applied to the target.
