摘要：
Hitting cold surfaces, such as aircraft ones, supercooled water droplets may freeze immediately. However, glaze ice may also be formed under some conditions: a part of the droplets may freeze, while the rest remains liquid, flowing on the substrate as a film. This paper proposes a model of a film created by the impact of supercooled droplets on a cylindrical obstacle. The film is a mixture of water and frazil ice, viz. a slurry. The film thickness and volume fraction of ice in the water are expressed by simple analytical formulas obtained from the mass and enthalpy balance laws in the presence of different phenomena responsible for film cooling. The results are compared with the data of existing experiments. © 2014 Springer Science+Business Media New York.
