A novel, asymptotic solution for a finite domain is developed for droplet freezing.
An enthalpy–porosity numerical model is also developed for verification of results.
Both approaches are validated with the experimental data yielding good comparison.
The applicability of the solution over a range of physical parameters has been evaluated.
The utility and the limitation of the perturbation solution has been discussed.
