A Level Set Method for the Simulation of Moving Contact Lines in Three Dimensions

Quan Zhao, Shixin Xu, Weiqing Ren

We propose an efficient numerical method for the simulation of multi-phase flows with moving contact lines in three dimensions. The mathematical model consists of the incompressibl…

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 Data Driven Method for Computing Quasipotentials

Bo Lin, Qianxiao Li, Weiqing Ren

The quasipotential is a natural generalization of the concept of energy functions to non-equilibrium systems. In the analysis of rare events in stochastic dynamics, it plays a cent…

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…
