Development and validation of a semi-analytical framework for droplet freezing with heterogeneous nucleation and non-linear interface kinetics
We present a novel, semi-analytical framework which accurately predicts every stage of
droplet freezing. Supercooling degree of the freezing droplet is computed by coupling the 1 …

Asymptotic analysis of a two-phase Stefan problem in an annulus with the convective boundary
The Stefan problem (whether in its classical form or not) has assumed that the interface
moves instantaneously with time as a prescribed initial condition. This assumption is valid in …
