From Lattice Boltzmann Method to Lattice Boltzmann Flux Solver [PDF]
Based on the lattice Boltzmann method (LBM), the lattice Boltzmann flux solver (LBFS), which combines the advantages of conventional Navier–Stokes solvers and lattice Boltzmann solvers, was proposed recently.

Numerical Modelling of Microchannel Gas Flows in the Transition Flow Regime Using the Cascaded Lattice Boltzmann Method [PDF]
In this article, a lattice Boltzmann (LB) method for studying microchannel gas flows is developed in the framework of the cascaded collision operator. In the cascaded lattice Boltzmann (CLB) method, the Bosanquet-type effective viscosity is employed to ...

Advection–Diffusion Lattice Boltzmann Method With and Without Dynamical Filter
In multi-component flow and/or thermal flows, when the diffusion coefficient of the advection–diffusion equation is relatively small, the relaxation coefficient in the lattice Boltzmann method will be close to 0.5, which will lead to numerical ...

A Multiple-Grid Lattice Boltzmann Method for Natural Convection under Low and High Prandtl Numbers
A multi-distribution lattice Boltzmann Bhatnagar–Gross–Krook (BGK) model with a multiple-grid lattice Boltzmann (MGLB) model is proposed to efficiently simulate natural convection over a wide range of Prandtl numbers. In this method, different grid sizes

Low Dissipative Entropic Lattice Boltzmann Method
In the entropic lattice Boltzmann approach, the stability properties are governed by the parameter α, which in turn affects the viscosity of a flow. The variation of this parameter allows one to guarantee the fulfillment of the discrete H-theorem for all

Hybrid Lattice Boltzmann Model for Nonlinear Diffusion and Image Denoising
In the present paper, a novel approach for image denoising based on the numerical solution to the nonlinear diffusion equation is proposed. The Perona–Malik-type equation is solved by employing a hybrid lattice Boltzmann model with five discrete ...

Modification of the lattice Boltzmann method for the computations of viscid incompressible fluid flows [PDF]
Modification of the lattice Boltzmann method for computation of viscous incompressible fluid flows is proposed. The method is based on the splitting of differential operator in Navier-Stokes equation and on the idea of instantaneous Maxwellisation of ...
