Lattice Boltzmann method for homogeneous and heterogeneous cavitation
Physical Review E, 2005The Shan and Chen single component multiphase lattice Boltzmann model is used to simulate homogeneous and heterogeneous cavitation. The simulations show excellent agreement with the equation of state for homogeneous cavitation and with energy considerations based on interface formation and bubble expansion for heterogeneous cavitation.

DNS of homogenous shear turbulence revisited with the lattice Boltzmann method
Journal of Turbulence, 2005Direct numerical simulations (DNSs) of homogenous shear turbulence are performed using the lattice Boltzmann method (LBM). This problem is revisited for two principle reasons: (i) to establish the validity of the LBM as an effective computational tool for turbulence; and (ii) to perform a detailed investigation of the dependence of the asymptotic state

Abstract A novel molecular collision based Lattice Boltzmann model at mesoscale was extended for representing hydrodynamics and concentration field of three typical reactive systems: (a) a reactive flow in a catalytic pore, (b) a fluid flow in a rectangular channel with a homogeneous reaction in the bulk and (c) a fluid flow that passes a reactive ...

International Journal for Numerical Methods in Fluids, 2008
AbstractA numerical method was developed for flows involving an interface between a homogenous fluid and a porous medium. The numerical method is based on the lattice Boltzmann method for incompressible flow. A generalized model, which includes Brinkman term, Forcheimmer term and nonlinear convective term, was used to govern the flow in the porous ...

We compare the lattice Boltzmann method (LBM) and Pseudo-Spectral (PS) method for direct numerical simulation of decaying homogeneous isotropic turbulence. In this study we use the generalized lattice Boltzmann equation (GLBE) with multiple-relaxationtime (MRT) collision model, which overcomes all the apparent defects in the popular lattice BGK ...

Abstract In this study, we present a numerical simulation on behavior of a liquid droplet on a heated horizontal substrate to investigate the contact line motion using multiphase Lattice Boltzmann method. For this purpose, the model of Lee is used which is applicable to a wide range of density ratios.

Abstract Dielectric permittivity is a prevailing property used for the estimation of water content in heterogeneous materials like soils and concrete. Troubles are frequently encountered when searching for the relationship between a material's permittivity and its degree of saturation.

A lattice Boltzmann high-density-ratio model, which uses diffuse interface theory to describe the interfacial dynamics and was proposed originally by Lee and Liu (J Comput Phys 229:8045–8063, 2010), is extended to simulate immiscible multiphase flows in porous media. A wetting boundary treatment is proposed for concave and convex corners.
