HEAT TRANSFER COEFFICIENT DURING SPRAY COOLING OF VERY HOT SURFACES BY FLAT NOZZLES
Original language description
An experimental investigation of spray cooling intensity was carried out to determine the heat transfer coefficient for different spray characteristics on a moving steel surface above the Leidenfrost point. The austenitic steel plate, which had an initial temperature of 1200°C, was cooled by a nozzle moving at a speed of 1 m·min-1 and spraying upwards onto the cooled surface at a distance of 250 mm. To discover the influence of different spray characteristics, flat nozzles were used, which can be sorted into two groups. Each group is comprised of one water nozzle and one mist nozzle tested at two air pressures. The first group operated with a water flow rate of 11 l·min-1 and the second group with a rate of 6 l·min-1 . The nozzles in each group were chosen to give different spray characteristics, while the water flow rate and spray angle are the same for the whole group, therefore the effect of the other parameters of the spray should be revealed and not the water flow rate only.
