Dr. David Sibley - Coupled dynamics of solid-liquid-vapour systems with mass transfer

Presented by Dr. David Sibley (Loughborough University)

In this talk we explore a regime where a droplet of liquid spreads over a solid and in the presence of a vapour, all of the same material (such as ice-water-water vapour). We consider dynamics where vapour can condense to liquid which in turn can freeze to solid throughout a droplet spreading process, and indeed vice-versa. By developing a thin-film model capturing phase-change, surface tension, density contrast, and interfacial potentials, a rich phase diagram will be explored---and complex dynamics such as layered solid growth driven by forces at the contact lines described [work in collaboration with Pablo Llombart (Universidad Complutense Madrid), Eva G. Noya (CSIC Madrid), Andrew J. Archer, and Luis G. MacDowell (Universidad Complutense Madrid); based on Nat. Commun. 12, 239 (2021)].
