A novel phase-field model for -phase problems: modeling, asymptotic analysis and numerical simulations
Lun Zhang, Chenxi Wang, Nan Lu +1
The classical phase-field modeling approaches for multiphase problems represent each phase using a regularized characteristic function, which necessarily introduces a simplex const…
Primal-dual splitting methods for phase-field surfactant model with moving contact lines
Wei Wu, Zhen Zhang, Chaozhen Wei
Surfactants have important effects on the dynamics of droplets on solid surfaces, which has inspired many industrial applications. Phase-field surfactant model with moving contact…
Onsager Principle-Based Domain Embedding for Thermodynamically Consistent Cahn-Hilliard Model in Arbitrary Domain
Wenkai Yu, Qi Wang, Zhen Zhang +1
The original Cahn-Hilliard model in an arbitrary domain with two prescribed boundary conditions is extended to a Cahn-Hilliard-type model in a larger, regular domain with homogeneo…
Thermodynamically Consistent Modeling and Stable ALE Approximations of Reactive Semi-Permeable Interfaces
Weidong Shi, Shixin Xu, Zhen Zhang +1
Reactive, semi-permeable interfaces play important roles in key biological processes such as targeted drug delivery, lipid metabolism, and signal transduction. These systems involv…
