A general formulation of phase-field models for nonisothermal solidification in multicomponent and multiphase alloy systems is derived from an entropy functional a thermodynamically consistent way. General expressions the free energy densities, diffusion coefficients, both weak faceted types surface kinetic anisotropy are possible. three-dimensional simulator developed to show capability model describe phase transitions, complex microstructure formation, grain growth polycrystalline textures.
Abstract 3D printing offers enormous flexibility in fabrication of polymer objects with complex geometries. However, it is not suitable for fabricating large structures geometrical features at the sub-micrometer scale. Porous structure scale can render macroscopic unique properties, including similarities biological interfaces, permeability and extremely surface area, imperative inter alia adsorption, separation, sensing or biomedical applications. Here, we introduce a method combining...
We present numerical simulations which support the formal asymptotic analysis relating a multiorder parameter Allen--Cahn system to multiphase interface problem with curvature-dependent evolution of interfaces and angle conditions at triple junctions. Within gradient energy system, normal an between phases i j is modeled by irreducible representations $(u_i\nabla u_j - u_j\nabla u_i)/{|u_i\nabla u_i|}$, where ui uj are ith jth components vectorial order $\bu\in \rz^N$. In case, dependence...
In this paper, we describe the derivation of a model for simulation phase transformations in multicomponent real alloys starting from grand-potential functional. We first point out limitations phase-field when evolution equations concentration and variables are derived free energy These mainly attributed to contribution grand-chemical-potential excess interface energy. For range applications, magnitude becomes large its influence on profiles dynamics is not negligible. The related constraint...
Abstract Precise control of the evaporation multiple droplets on patterned surfaces is crucial in many technological applications, such as anti‐icing, coating, and high‐throughput assays. Yet, complex process well‐defined still poorly understood. Herein, we develop a digital twin system for real‐time monitoring key processes droplet microarray (DMA), which essential parallelization automation operations cell culture. Specifically, investigate nanoliter under different conditions via...
A nonisothermal phase field model for alloys with multiple phases and components is derived. The allows arbitrary diagrams. We relate the to classical sharp interface models by formally matched asymptotic expansions. In addition we discuss several examples our ones already existing.
The wetting effect has attracted great scientific interest because of its natural significance as well technical applications. Previous models mostly focus on one-component fluids or binary immiscible liquid mixtures. Modelling the phenomenon for multicomponent and multiphase is a knotty issue. In this work, we present thermodynamically consistent diffuse interface model to describe ternary fluids, an extension Cahn's theory fluids. particular, consider both miscible For validate equilibrium...
