Finite-element simulations of interfacial flows with moving contact lines
… method in the finite-element framework for interfacial flows with moving contact lines. In our method, the contact line is advected naturally by the flow field. Contact angle hysteresis can be easily implemented without explicit calculation of the contact angle or the contact line velocity, …

Mean-Field Free-Energy Lattice Boltzmann Method for Liquid-Vapor Interfacial Flows
… numerical development to simulate liquid-vapor flows and the applications to microchannels. First, we obtain a consistent non-local pressure equation for simulating liquid-vapor interfacial flows using mean-field free-energy theory. This new pressure equation is shown to be the general form of …

Finite Element Simulation of Interfacial Flows on Unstructured Meshes using a Second-order Accurate VOF Method
… first part a two-dimensional numerical model of interfacial flow phenomena has been developed, consisting of a finite element discretization of the time-dependent Navier-Stokes equations for immiscible, Newtonian, laminar, isothermal incompressible flows, with a volume-of-fluid (VOF) technique …

Direct computations of marangoni driven flows using a volume of fluid method
… have been used for simulating a wide range of interfacial flows. An improved accuracy of the surface tension force computation has enabled the VoF method to become widely used for simulating flows driven by the surface tension force. A general methodology for the inclusion of variable surface …

A Higher-Order VOF Interface Reconstruction Scheme for Non-Orthogonal Structured Grids - with Application to Surface Tension Modelling
… for the purpose of simulating liquid-gas interfacial flows numerically. The key strength of VOF is its mass conserving property. However, interface reconstruction is required when geometric properties such as curvature need to be accurately computed. For surface tension modelling in …

Mathematical problems arising in interfacial electrohydrodynamics
… and complex nonlinear dynamics including chaotic interfacial oscillations. It is established that a sufficiently high electric field will drive the system to chaotic oscillations, even when the Reynolds number is smaller than the critical value below which the non-electrified problem is linearly …
