“…As an alternative to the existing methods widely used for cooling high-temperature surfaces, it is proposed to use a two-component dispersed water-gas coolant flow [4][5][6][7][8][9][10]. Previously conducted experimental studies [7][8] of the features of the cooling process with such a coolant have so far concerned the case when the coolant flow interacted with the cooled surface at an acute angle (~ 3-5 degrees).…”

The cooling of surfaces that perceive high heat fluxes (more than 7 MW/m2) at the current pace of development of the energy sector will become one of the main problems of the near future. In this paper, as one of the options for effective cooling of high-temperature surfaces of various geometries, the results of an experimental study of the cooling process by a spray flow directed perpendicular to the cooled surface are presented. Two different types of nozzles are used for cooling. Water consumption varied in the range (8.3÷25.0)∙10−3kg/s, air consumption in the range (0.3÷1.1)∙10−3kg/s. The maximum value of the density of the removed heat flux for one of the nozzles is 11.3 MW/m2 at a water flow rate 25.0∙10−3kg/s, the average value of the heat transfer coefficient during spray cooling was about 100 kW/m2K.
