A Thermodynamically-Consistent Phase Field Crystal Model of Solidification with Heat Flux
文献摘要：
In this paper we describe a new model for solidification with heat flux us-ing the phase field crystal(PFC)framework.The equations are thermodynamically consistent in the sense that the time rate of change of the entropy density is positive in the bulk and at the boundaries of the domain of interest.The resulting model con-sists of two equations,a heat-like equation and a mass-conservation equation that de-scribes how the atom density changes in time and space.The model is simple,yet it can properly capture the variation in the free energy landscape as the temperature is changed.We describe the procedure for constructing a temperature-atom-density phase diagram using this energy landscape,and we give a simple demonstration of solidification using the model.
