RISGeneral velocity, pressure, and initial condition for two-dimensional and three-dimensional lattice Boltzmann simulations
In this paper, an alternative approach to implement initial and boundary conditions in the lattice Boltzmann method is presented. The main idea is to approximate the nonequilibrium component of distribution functions as a third-order power series...
A lattice Boltzmann method to simulate combined radiation–force convection heat transfer mode
Lattice Boltzmann method is extended to solve a combined mode of radiation and force convection heat transfer problem in a channel. Effects of different parameters such as radiation parameters, Peclet number, and emissivity on temperature...
Two relaxation time lattice Boltzmann equation for high Knudsen number flows using wall function approach
In the present study, we investigate gas flow in a micro-/nanochannel by using the two relaxation time lattice Boltzmann equation (TRT-LBE). The wall function approach is employed in order to consider the effect of Knudsen layer in transition flow...
Lattice Boltzmann simulation of a Cu-water nanofluid filled cavity in order to investigate the influence of volume fraction and magnetic field specifications on flow and heat transfer
In the present study, a nanofluid filled cavity with sinusoidal temperature boundary condition was investigated numerically. The LBM method was applied to simulate the Cu-water nanofluid flow under the influence of an ...
Taguchi design of three dimensional simulations for optimization of turbulent mixed convection in a cavity
orthogonal array with each trial performed under different conditions of position of the cylinder, Reynolds number (Re) and Rayleigh number (Ra). The thermal lattice Boltzmann based on D3Q19 methods without any turbulent submodels was purposed to simulate...
