A modelling study on the evaporative freezing process of water droplets was carried out in this paper in order to better understand artificial snowmaking and, as a result, to improve machine design. To accomplish this, mass and heat transfer theoretical models of a single water droplet cooling in an air space were devised and implemented in a numerical model created with the software COMSOL Multiphysics. On this process, the impacts of air temperature, relative humidity, and velocity, as well as the initial diameter and temperature of water droplets, were found and analysed, and their optimum ranges for snowmaking were determined.
