Abstract—

A set of activities aimed at upgrading an experimental bench simulating heavily loaded components of thermonuclear facilities is accomplished. The design of a test section for implementing one-sided heating with high energy density is developed. A VCh-60AV high-frequency generator with operating frequencies of 30–60 kHz is the test section heating system’s key component. The article describes the experimental bench schematic design, hydraulic circuit components, and the high-frequency heating system and measurement system components. The schematic design of a hydraulic atomizer with a conical insert, which generates a sprayed flow in carrying out experimental studies is presented. The results of field velocity measurements in the atomizer spray jet and of experimental study of sprayed flow distribution over the droplet radius are given, and the average diameter of droplets in the spray jet section was determined, which was found to be 34 μm. The techniques for carrying out experiments on thermal stabilization in a steady mode by spray cooling and for processing the primary experimental data are described. The effectiveness of high-temperature surface thermal stabilization by a spray of distilled water at a coolant gauge pressure of (0.2–0.6) × 106 Pa, coolant mass flowrate (3.3–6.15) × 10–3 kg/s, and spray density within the range from 1.67 to 3.11 kg/(m2 s) is studied. The obtained experimental data array is processed, and the graphic dependences of heat flux and heat-transfer coefficient on the temperature difference between the cooled wall and coolant spray are presented. The heat flux in the experimental study reached 3.2 MW/m2, and the heat-transfer coefficient in that case was equal to 77 kW/(m2 K). The obtained experimental data show satisfactory repeatability in a wide range of temperature difference from 0 to 400°C, and high heat flux and heat-transfer values have been reached.
