Initial and Boundary Conditions for the Lattice Boltzmann Method [PDF]
, 1993 A new approach of implementing initial and boundary conditions for the lattice Boltzmann method is presented. The new approach is based on an extended collision operator that uses the gradients of the fluid velocity.

Lattice Boltzmann methods and active fluids [PDF]
The European Physical Journal E, 2019 We review the state of the art of active fluids with particular attention to hydrodynamic continuous models and to the use of Lattice Boltzmann Methods (LBM) in this field. We present the thermodynamics of active fluids, in terms of liquid crystals modelling adapted to describe large-scale organization of active systems, as well as other effective ...

The Physics of Fluids, 2020 In this paper, a three-dimensional (3D) cascaded lattice Boltzmann method (CLBM) is implemented to simulate the liquid–vapor phase-change process. The multiphase flow field is solved by incorporating the pseudopotential multiphase model into an improved ...

Modeling realistic multiphase flows using a non-orthogonal multiple-relaxation-time lattice Boltzmann method [PDF]
The Physics of Fluids, 2019 In this paper, we develop a three-dimensional multiple-relaxation-time lattice Boltzmann method (MRT-LBM) based on a set of non-orthogonal basis vectors.

Modification of the lattice Boltzmann method for the computations of viscid incompressible fluid flows [PDF]
Компьютерные исследования и моделирование, 2014 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 ...

Modeling of natural convection by lattice Boltzmann in a partially heated cavity [PDF]
E3S Web of Conferences, 2023 This study introduces the lattice Boltzmann method for modeling natural convection in a partially heated square cavity filled with air for varying Rayleigh numbers. A temperature gradient affects the vertical walls, whereas the other walls are treated as

Parametric lattice Boltzmann method [PDF]
Journal of Computational Physics, 2017 The discretized equilibrium distributions of the lattice Boltzmann method are presented by using the coefficients of the Lagrange interpolating polynomials that pass through the points related to discrete velocities and using moments of the Maxwell-Boltzmann distribution.

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 ...
