Freezing of spherical droplets in the environment of cold air

The problem of spherical droplets freezing in a stream of cold air is considered.Generalized equation for finding the depth of freezing of the spherical layer depends on time and thermo physical properties of the fluid was proposed.The full period time of spherical layer freezing consists of two parts: the first is preliminary cooling of droplet down to the phase change temperatures and the second period connects with freezing spherical layer time.The description of the experimental installation and the obtained experimental data were presented.The theoretical generalization was conformed with the theory.
