Innovative method of cooling and thermostabilization of tokamak elements with capillary-porous structures

The paper describes and considers the possibility of using the method of cooling by a gas-water spray of a working area heated by a beam of charged particles. The design of a gas-water spray generator and an experimental installation for visualizing the process of outflow of the working environment from it has been developed, the necessary components of the system have been prepared, and an experimental setup has been installed. The cooling of the surface is carried out by evaporation of the impalpable drops of water from spray flow. Photographs of coolant outflow from the gas-water spray generator were obtained. The experiments revealed that the dispersion of liquid drops in the spray flow increases with air pressure rise, with a constant water consumption. It was concluded from the experiments carried out that the optimum dispersity of drops is achieved at air pressure (2÷3)·105 Pa and water flow (50÷100) g/s. (paper)
