Lattice BGK Models for the Navier-Stokes Equation: Nonlinear Deviation in Compressible Regimes
Yuehong Qian,Steven A. Orszag +1 more
TL;DR: In this paper, a nonlinear deviation from the Navier-Stokes equation is obtained from the recently proposed LBGK models, which are designed as an alternative to lattice gas or lattice Boltzmann equation.

Design of acoustic trim based on geometric modeling and flow simulation for non-woven
TL;DR: In this article, the acoustic properties of a stacked fiber non-woven are modeled by a macroscopically homogeneous random system of straight cylinders (tubes), and the flow is computed in digitized realizations of the stochastic geometric model using the lattice Boltzmann method.

Pore-scale modeling of complex transport phenomena in porous media
Li Chen,Bengkel Mecca Medina,An He,Jianlin Zhao,Qinjun Kang,Zeng-Yao Li,Jan Carmeliet,Naoki Shikazono,Wen-Quan Tao +8 more
TL;DR: Pore-scale modeling is an efficient tool for the simulation of porescale transport and reactions in porous media because of its ability to accurately characterize these processes and to provide the distribution details of important variables which are challenging for current experimental techniques to provide either due to lack of in-situ measurement capability or due to limited spatial and temporal resolution as discussed by the authors.

Numerical simulations of single phase reacting flows in randomly packed fixed-bed reactors and experimental validation
Hannsjörg Freund,Thomas Zeiser,Florian Huber,Elias Klemm,Gunther Brenner,Franz Durst,Gerhard Emig +6 more
TL;DR: In this article, a Monte-Carlo method was used to generate realistic random packings of spherical particles, and the subsequent numerical simulation of the 3D flow field and coupled mass transport of reacting species is done by means of lattice Boltzmann methods.

Stabilization of thermal lattice Boltzmann models
TL;DR: In this paper, a three-dimensional thermal lattice Boltzmann model with two relaxation times to separately control viscosity and thermal diffusion is developed and the numerical stability of the model is significantly improved using Lax-Wendroff advection to provide and adjustable time step.

A Model for Collision Processes in Gases. I. Small Amplitude Processes in Charged and Neutral One-Component Systems
TL;DR: In this paper, a kinetic theory approach to collision processes in ionized and neutral gases is presented, which is adequate for the unified treatment of the dynamic properties of gases over a continuous range of pressures from the Knudsen limit to the high pressure limit where the aerodynamic equations are valid.

Lattice-Gas Automata for the Navier-Stokes Equation
TL;DR: It is shown that a class of deterministic lattice gases with discrete Boolean elements simulates the Navier-Stokes equation, anc, and can be used to design simple, massively parallel computing machines.

Boltzmann Approach to Lattice Gas Simulations
F. J. Higuera,Javier Jiménez +1 more
TL;DR: In this article, an alternative simulation procedure for lattice hydrodynamics based on the lattice Boltzmann equation instead of on the microdynamical evolution is proposed, where the averaging step, used by the latter method to derive macroscopic quantities, is suppressed, as well as the associated fluctuations.
