To achieve the net-zero target, hydrogen (H 2) will emerge as an essential cornerstone
within the energy supply chain of the future. To effectively attain such a target for an …

The contact angle dynamics between a two-phase interface and a solid surface is important
in physical interpretations, mathematical modeling, and numerical treatments. We present a …

We propose a front-tracking method that considers a moving contact line with a generalized
Navier boundary condition (GNBC) and with a delta function distribution approximated on …

A preliminary numerical simulation of the microscopic two-phase fluid motion on a solid
surface was conducted using an interface-tracking method based on the phase-field model …

The applicability of a numerical method is preliminarily examined to determine its suitability
for simulations of microscopic immiscible liquid-liquid motion on solid walls, which is used …

We focused on the attenuation of air-water interface oscillation for impinged water droplets
freezing on a cooling surface. We carried out not only experiments but also two-dimensional …

Droplet movement by electrowetting on dielectric (EWOD) in a Hele-Shaw cell is analysed
theoretically and numerically. We propose a simple theoretical model for the motion, which …

Applicability of two kinds of computational-fluid-dynamics method adopting Cahn-Hilliard
(CH) and Allen-Cahn (AC)-type diffuse-interface advection equations based on a phase …

In this thesis capillary dominated two–phase flow is studied by means of numerical
simulations and experiments. The theoretical basis for the simulations consists of a phase …

A parabolic free boundary problem with an obstacle and a volume constraint is analyzed.
The equation models slow motion of droplets on nonhomogeneous surfaces. We show …
