The Performance Analysis of Single Water Droplet Evaporative Supercooled Process for Ice Slurry Production

Abstract:

To analyze evaporative supercooled process of single water droplet in the air with low temperature and low humidity ratio, a mathematical model was constructed to simulate the evaporative process of single water droplet. The droplet temperature during its evaporation process and the influence of different initial droplet diameter, initial water temperature, air temperature and air humidity ratio were analyzed. The evaporative process of droplet in supercooled stage was simulated through the mathematical model, results from modeling basically tallies with the experiment. The numerical results show that lower initial temperature of water droplet can lessen the supercooled time of reaching steady state evaporation stage. Additionally it can not only lessen the supercooled time but also acquire lower supercooled temperature of water droplet by reducing air humidity ratio or lowering air temperature. Furthermore, the smaller initial diameter of water droplet is, the shorter supercooled time of reaching steady state evaporation stage becomes.
