Diffuse and sharp interface models represent two alternatives to describe phase transitions with an interface between two coexisting phases. The two model classes can be independently formulated. Thus there arises the problem whether the sharp limit of the diffuse model fits into the setting of a ...
Those techniques can be categorized into two main groups: sharp interface, and diffuse interface methods. For sharp interface models involving two phases [20–23], the governing equations for each phase are written separately and additional jump conditions are considered at the interface to satisfy ...

VOF and Phase Change: Actually you need to have a diffuse interface otherwise you do not have any mass transfer. Now show with nodes values OFF the VOF distribution in the interfacial cells (perhaps a time mean). June 28, 2021 at 10:24 am b404957074 Subscriber Here you go, after swi...
Since VOFM involves a geometric method to reconstruct the interface, implementation of this method for 3D problems is difficult. PFM is derived from minimization of free energy functional, employing a diffuse interface between the two phases. The application of this method on a Stefan problem is ...
sharp interface, while Sample 2 has a diffuse interface. The interface structure of Al/Si Sample 1 is shown in Fig.2a, showing the interface between Al and Si is atomically sharp, with only 1–2 distorted layers of interface atoms observed. The cross-sectional HAADF-STEM image of Al/Si ...
5c). By keeping the solution under static conditions (i.e., without agitation), as the etching proceeds, the etching species only diffuse from the bulk solution surrounding the silicon sample to replenish the solution contained within the spaces between the pillars. As a result, the sharpening ...
