InterfaceEquilibrium_SplitDilatation – A modified version of the above model, which splits the liquid and vapor portions of the dilatation rate, and applies them on the respective sides of the interface (Rattner, 2015). This approach yields better conservation of the two phases, and reduces smearing of the interface during evaporation.

A novel model of third phase inclusions on two phase

Feb 22, 2010 · Through scaling arguments and numerical computations, we demonstrate that the Cahn–Hilliard model approaches a sharp-interface limit when the interfacial thickness is reduced below a threshold while other parameters are fixed. In this limit, the contact line has a diffusion length that is related to the slip length in sharp-interface models.

MULTISCALE MODELING OF SOLIDIFICATION: PHASE-FIELD

information is obtained by the proposed first-principle based modeling and simulation procedure. On the scientific side, the approach accurately tracks the moving melt-front (modeled as a sharp liquid-solid interface) and provides all necessary information about the time-varying heat-flow rates, temperature profiles, stored thermal energy, etc.
