Abstract
Two relevant computational models, one relying on a Level-Set approach, the other one on a Volume-of-Fluid tracking procedure with piecewise linear interface reconstruction, are comparatively assessed in terms of their capability to simulate crystallization of supercooled water. The models are preliminary validated by computing a one-dimensional freezing front propagation for which an analytic solution exists. Afterwards, the tip velocity of two-dimensional dendrites growing in supercooled water is determined and compared with corresponding experimental results and theoretical predictions in the range of supercooling between 1K and 30K. Present modeling results following closely both the underlying theory and experimental findings show very good mutual agreement.
