Spreading of Micrometer-Sized Droplets under the Influence of Insoluble and Soluble Surfactants: A Numerical Study

open access: yesColloids and Interfaces, 2019
Wetting and spreading of surfactant solutions play an important role in many technical applications. In printing processes, the size of individual droplets is typically on the order of a few tens of microns.

Development of numerical method for mass transfer from a buoyant bubble under a high Schmidt number condition

open access: yesNihon Kikai Gakkai ronbunshu, 2016
Under a high Schmidt number condition, concentration boundary layers get much thinner than momentum boundary layers. Resolution requirement to numerically capture the steep concentration gradient near an interface is therefore significantly high.

Adjoint complement to the volume-of-fluid method for immiscible flows [PDF]

open access: yesJournal of Computational Physics, 2021
The paper is concerned with an adjoint complement to the Volume-of-Fluid (VoF) method for immiscible two-phase flows, e.g. air and water, which is widely used in marine engineering due to its computational efficiency. The particular challenge of the primal and the corresponding adjoint VoF-approach refers to the sharp interface treatment featuring ...

A minimal model for acoustic forces on Brownian particles [PDF]

open access: yes, 2013
We present a generalization of the inertial coupling (IC) [Usabiaga et al. J. Comp. Phys. 2013] which permits the resolution of radiation forces on small particles with arbitrary acoustic contrast factor.

Modeling liquid droplet impact on a micropillar-arrayed viscoelastic surface via mechanically averaged responses

open access: yesEngineering Applications of Computational Fluid Mechanics, 2023
Droplet impact on a substrate is an intriguing phenomenon that widely exists in our daily life and a broad range of industrial processes. However, droplet impact dynamics on soft textured surfaces are less explored and the underlying mechanisms remain ...
