Outline
Icing in the form of impinging supercooled droplets accounts for the most cases of aircraft icing. This review provides an in-depth discussion over single sessile droplet icing, impinging of a droplet, and the combined icing of an impinging droplet. Special focus is placed on icing of an impinging supercooled large droplet, which is of significant importance in the study of aircraft icing. The effects of a few key parameters, such as the impinging speed and droplet size, are studied and analyzed. Meanwhile, by studying the factors influencing the dynamics of droplet impact icing, the icing phenomena of room temperature droplets and supercooled droplets are investigated, and it turns out that the initial thermophysical properties, heat transfer mechanisms and phase transition modes vary drastically, and the kinetic behaviors such as nucleation time, ice crystal type, interfacial heat transfer characteristics and phase advancing velocity as well as the droplet morphology are significantly different. The effects of the impact velocity, particle size and surface wetting on droplet impact icing are indicated, providing a theoretical basis and reference for the design and development of anti-deicing technology for aircraft.
