Journal ArticleDOI
Contact line and contact angle dynamics in superhydrophobic channels.
Junfeng Zhang,Daniel Y. Kwok +1 more
TL;DR: A better understanding of dynamic wetting and fluid flow behaviors over superhydrophobic surfaces is provided and two regimes were found for the flow velocity as a function of surface roughness, related directly to the balance between driving force and flow resistance.
Journal ArticleDOI
A 2D lattice Boltzmann study on electrohydrodynamic drop deformation with the leaky dielectric theory
Junfeng Zhang,Daniel Y. Kwok +1 more
TL;DR: In this paper, a series of drop deformation simulations under the influence of an electric field were carried out, and the results were in good agreement with other theoretical and experimental studies.
Journal ArticleDOI
Mean-field free-energy approach to the lattice Boltzmann method for liquid-vapor and solid-fluid interfaces.
TL;DR: This mean-field approach to LBM provides more realistic contact angles and fluid density profiles near the vicinity of an impenetrable wall which cannot be easily obtained by other LBM schemes.
Journal ArticleDOI
Apparent slip over a solid-liquid interface with a no-slip boundary condition
Junfeng Zhang,Daniel Y. Kwok +1 more
TL;DR: This work relates interfacial slip to a more realistic solid-fluid interaction and hence contact angle and the kinetic nature of LBM is manifested in this interfacial study.
Journal ArticleDOI
Lattice Boltzmann Study on the Contact Angle and Contact Line Dynamics of Liquid−Vapor Interfaces
Junfeng Zhang,Daniel Y. Kwok +1 more
TL;DR: These simulations demonstrated that incorporating interfacial effects into the lattice Boltzmann model can be a valuable and powerful alternative in interfacial studies.
