Study on optimum air-water ratio of periodic spray evaporative cooling

Spray evaporative cooling is an efficient method for cooling. Studies the influence of the change of optimum air-water ratio in periodic spray evaporative cooling process on heat transfer performance of heat exchangers with experimental method. The result shows that under different air-water total pressures and different water supply temperatures, there is an optimum air-water ratio 1.0. Correspondingly, the mass ratio of air-water is 0.31.
