THE PERFORMANCE ANALYSIS OF SINGLE WATER DROPLET EVAPORATIVE SUPERCOOLED PROCESS FOR ICE SLURRY PRODUCTION
To analyze the evaporative super-cooled process of single water droplet in the air with low temperature and low humidity ratio, a mathematical model for the heat and mass transfer process of droplet was proposed. The water droplet temperature during its evaporation process and the influences of initial water droplet diameter, initial water temperature, air temperature and air humidity ratio were analyzed. The evaporation process of water droplet in supercooled stage was simulated by the mathematical model, results from modeling basically tallies with experiment. The numerical results show that both lower initial temperature of water droplet and temperature of air can lessen the super-cooled time of water droplet. Additionally, it can also lessen the super-cooled time of water droplet and acquire lower super-cooled temperature of water droplet by reducing the humidity ratio of air. Furthermore, the smaller initial diameter of water droplet is, the shorter super-cooled time of water droplet becomes. The evaporation investigation of water droplet can provide a necessary theoretical foundation for design of a novel ice slurry producing system which produces ice by utilizing liquid dehumidification evaporative super-cooled water method.
