  • We present a novel crystal growth model coupled with a heterogeneous nucleation model to investigate the dynamics of a recalescence stage during droplet freezing. 
  • A statistical framework is developed for the sensitivity analysis that uses the Monte-Carlo method to quantify the influence of self-diffusivity and the interface kinetic factor on the crystal growth rate, rigorously. 
  • The model parameters are optimized using the minimization of the sum of the least-squares method. 
  • The proposed crystal growth model along with the optimized parameters can reliably simulate linear and nonlinear interface kinetics for metastable water of supercooling up to 30 K.
