Advances in Modeling of Chrystal Nucleation from the Melt

Two contributions to the modeling of nucleation are discussed here. The temperature dependence of the crystal–melt interfacial tension can be introduced by scaling of the interfacial parameters to the entropy and enthalpy of fusion. A new simulation of nucleation during solidification in a gas-filled drop tube is discussed. It computes the temperature distribution and convection in the drop and allows introduction, stochastically in space and time, of multiple nuclei with interfering thermal fields.
