A Thermodynamically Consistent Model and Its Conservative Numerical Approximation for Moving Contact Lines with Soluble Surfactants
Quan Zhao, Weiqing Ren, Zhen Zhang
We derive a continuum sharp-interface model for moving contact lines with soluble surfactants in a thermodynamically consistent framework. The model consists of the isothermal two-…
A Finite Element Method for Electrowetting on Dielectric
Quan Zhao, Weiqing Ren
We consider the problem of electrowetting on dielectric (EWoD). The system involves the dynamics of a conducting droplet, which is immersed in another dielectric fluid, on a dielec…
An energy-stable parametric finite element method for simulating solid-state dewetting
Quan Zhao, Wei Jiang, Weizhu Bao
We propose an energy-stable parametric finite element method (ES-PFEM) for simulating solid-state dewetting of thin films in two dimensions via a sharp-interface model, which is go…
An Energy-stable Finite Element Method for the Simulation of Moving Contact Lines in Two-phase Flows
Quan Zhao, Weiqing Ren
We consider the dynamics of two-phase fluids, in particular the moving contact line, on a solid substrate. The dynamics are governed by the sharp-interface model consisting of the…
A parametric finite element method for solid-state dewetting problems in three dimensions
Quan Zhao, Wei Jiang, Weizhu Bao
We propose a parametric finite element method (PFEM) for efficiently solving the morphological evolution of solid-state dewetting of thin films on a flat rigid substrate in three d…
Sharp-interface model for simulating solid-state dewetting in three dimensions
Wei Jiang, Quan Zhao, Weizhu Bao
The problem of simulating solid-state dewetting of thin films in three dimensions (3D) by using a sharp-interface approach is considered in this paper. Based on the thermodynamic v…
