Lattice Boltzmann simulation of droplet behaviour in microfluidic devices [PDF]

, 2008
We developed a lattice Boltzmann model to investigate the droplet dynamics in microfluidic devices. In our model, a stress-free boundary condition was proposed to conserve the total mass of flow system and improve the numerical stability for flows with ...

Lattice Boltzmann phase-field modeling of thermocapillary flows in a confined microchannel [PDF]

, 2014
To understand how thermocapillary forces manipulate the droplet motion in a confined microchannel, a lattice Boltzmann phase-field model is developed to simulate immiscible thermocapillary flows with consideration of fluid–surface interactions.

High-Accuracy Approximation of High-Rank Derivatives: Isotropic Finite Differences Based on Lattice-Boltzmann Stencils

The Scientific World Journal, 2014
We propose isotropic finite differences for high-accuracy approximation of high-rank derivatives. These finite differences are based on direct application of lattice-Boltzmann stencils.

A Three-Dimensional Semiclassical Lattice Boltzmann Method for Lid-Driven Cubic Cavity Flows

Journal of Fluid Science and Technology, 2011
A three-dimensional lattice Boltzmann method based on the Uehling-Uhlenbeck Boltzmann-BGK equation is presented. The method is directly derived by projecting the kinetic governing equation onto the tensor Hermite polynomials and various hydrodynamic ...
