To analyze the evaporation characteristics of single water droplet in low temperature and low humidity ratio air in ice production system with evaporative supercooled water

a mathematical model of evaporative supercooling process of single water droplet was proposed.The evaporation process of droplet in supercooling stage was simulated with theoretical model and the results are basically consistent with the experiment on suspended single water droplet

so it is feasible to predict the evaporative supercooling characteristics of small water droplet by the mathematical model.The influence of initial diameter and temperature of water droplet

air temperature

humidity ratio of air

and air velocity on the temperature of water droplet during its evaporative supercooling process was analyzed.The numerical results show that smaller diameter and lower temperature of water droplet and larger air velocity can increase the cooling rate of water droplet and shorten the supercooling time reaching steady state evaporation stage.Additionally

lowering the temperature or humidity ratio of air can not only improve the cooling rate of water droplet

but also increase the supercooling degree of water droplet reaching steady state evaporation stage.The investigation of evaporative supercooling process of water droplet can provide a foundation for improving the efficiency of ice production and optimal design for ice-making system with evaporative supercooled water.
