How ice grows from premelting films and water droplets

D. N. Sibley, P. Llombart, et al.

Discover how a mesoscopic model can illuminate the delicate interplay between ice growth and melting near the triple point! This research by David N. Sibley, Pablo Llombart, Eva G. Noya, Andrew J. Archer, and Luis G. MacDowell unveils fascinating growth regimes driven by a quasi-liquid layer on ice surfaces.

Abstract
Close to the triple point, the surface of ice is covered by a thin liquid layer (quasi-liquid layer) impacting growth and melting rates. This paper develops a mesoscopic model of liquid-film mediated ice growth, identifying various growth regimes. At low saturation, freezing proceeds by terrace spreading; at higher saturations, water droplets condense, forming a crater below, and freezing occurs beneath the droplet. This model offers a framework for understanding freezing near three-phase coexistence and provides a first-principle theory of ice growth and melting.
