A LATTICE BOLTZMANN FOR DISORDERED FLUIDS

International Journal of Modern Physics B, 2003
A variant of the lattice Boltzmann scheme is presented as a mesoscopic model of glassy behavior. A hierarchical density-dependent interaction potential is introduced, which allows the coexistence and competition of multiple density minima. We find that this competition allows to model geometrical frustration which produces disordered patterns with ...

Numerical simulation of compressible flows by lattice Boltzmann method

Numerical Heat Transfer, Part A Applications, 2019
In this article, we propose a numerical framework based on multiple relaxation time lattice Boltzmann (LB) model and novel discretization techniques for simulating compressible flows.

Theory of the lattice Boltzmann method: Lattice Boltzmann models for nonideal gases

Physical Review E, 2000
In this paper a procedure for systematic a priori derivation of the lattice Boltzmann models for nonideal gases from the Enskog equation (the modified Boltzmann equation for dense gases) is presented. This treatment provides a unified theory of lattice Boltzmann models for nonideal gases.

Lattice Boltzmann equation hydrodynamics

Physical Review E, 2001
By inserting position and time dependent "source" or "forcing" terms into the microscopic evolution equation of a lattice Boltzmann fluid and treating the generalized scheme within the usual Chapman-Enskog methodology, we show that the emergent dynamics of the lattice fluid may be usefully transformed.

Lattice Boltzmann model for compressible flows on standard lattices: Variable Prandtl number and adiabatic exponent.

Physical Review E, 2019
A lattice Boltzmann model for compressible flows on standard lattices is developed and analyzed. A consistent two-population thermal lattice Boltzmann is used which allows a variable Prandtl number and a variable adiabatic exponent, and appropriate ...

A Lattice Boltzmann Method for Image Denoising

IEEE Transactions on Image Processing, 2009
In this paper, we construct a Lattice Boltzmann scheme to simulate the well known total variation based restoration model, that is, ROF model. The advantages of the Lattice Boltzmann method include the fast computational speed and the easily implemented fully parallel algorithm. A conservative property of the LB method is discussed. The macroscopic PDE

Rectangular lattice Boltzmann method

Physical Review E, 2010
A set of rectangular lattice Boltzmann methods for fluid flows is developed. It is shown that reformulating local equilibrium distribution functions can result in the rectangular lattice Boltzmann models without the aid of an interpolation for shallow water equations, Navier-Stokes equations, and axisymmetric flow equations.

Simplified lattice Boltzmann method for non‐Newtonian power‐law fluid flows

International Journal for Numerical Methods in Fluids, 2019
In this paper, we present a simplified lattice Boltzmann method for non‐Newtonian power‐law fluid flows. The new method adopts the predictor‐corrector scheme and reconstructs solutions to the macroscopic equations recovered from the lattice Boltzmann ...
