We verify the accuracy and the truncation errors of approximation to the first derivatives and to Laplacian operator in the lattice Boltzmann method. The truncation errors are calculated by the Taylor series expansion, and the influences are analytic

In this paper, we propose a lattice Boltzmann model for simulation of two-phase flows pertinent to thermal nonideal fluids in two dimensions. This LBM has a modified pseudo-potential so that it recovers a full set of hydrodynamic equations for two-ph

In this paper, the lattice Boltzmann method (LBM) is applied to simulation of natural convection in porous media using Brinkman-Forchheimer equation. The Brinkman-Forchheimer equation is recovered from a kinetic equation for the density distribution

In a car under summer solar radiation, it is well known that temperature become very high and is found to be over 90 degrees C on the top of the front dashboard and also air temperature around the driver's seat were over 65 degrees C. Thus, a ventila
