Enthalpy method for the solidification of a supercooled liquid
Technical Report
·
OSTI ID:5855987
The classical enthalpy formulation of phase change processes does not permit modeling solidification of supercooled liquids. This report describes an enthalpy-based method for simulating a freezing process involving a planar front moving into a supercooled but not hypercooled liquid. The method is applicable when the liquid is initially below its equilibrium freezing temperature, T/sub cr/, but above T/sub cr/ - H/c/sub L/. Here H and c/sub L/ are the latent heat of solidification and the specific heat of the liquid respectively. The report also discusses a computer implementation of the method in one-dimension and results of its application to a particular problem with an explicit solution. 10 refs., 3 tabs.
