Toward a Lattice Boltzmann Method for Solids—Application to Static Equilibrium of Isotropic Materials

Applied Sciences, 2022
This work presents a novel method for simulating the behavior of solid objects with the Lattice Boltzmann Method (LBM). To introduce and validate our proposed framework, comparative studies are performed for computing the static equilibrium of isotropic ...

Investigation of hydrodynamic parameters inside a gas centrifuge rotor in the presence of hydrogen fluoride and air light gases using DSMC and Boltzmann distribution function [PDF]

مجله علوم و فنون هسته‌ای, 2020
The Boltzmann equation which describes binary collisions between molecules is a very important equation in physics and fluid dynamics. Direct Monte Carlo simulation is one of the methods to solve the Boltzmann equation. The moisture can leak to the fluid

Fluctuating Multicomponent Lattice Boltzmann Model [PDF]

, 2015
Current implementations of fluctuating lattice Boltzmann equations (FLBE) describe single component fluids. In this paper, a model based on the continuum kinetic Boltzmann equation for describing multicomponent fluids is extended to incorporate the ...

Test of Information Theory on the Boltzmann Equation [PDF]

, 2003
We examine information theory using the steady-state Boltzmann equation. In a nonequilibrium steady-state system under steady heat conduction, the thermodynamic quantities from information theory are calculated and compared with those from the steady ...

Jeans instability from post-Newtonian Boltzmann equation

European Physical Journal C: Particles and Fields, 2021
Jeans instability within the framework of post-Newtonian Boltzmann and Poisson equations are analyzed. The components of the energy–momentum tensor are calculated from a post-Newtonian Maxwell-Jüttner distribution function.

Hilbert Expansion from the Boltzmann equation to relativistic Fluids [PDF]

, 2010
We study the local-in-time hydrodynamic limit of the relativistic Boltzmann equation using a Hilbert expansion. More specifically, we prove the existence of local solutions to the relativistic Boltzmann equation that are nearby the local relativistic ...

Boundary Layers and Shock Profiles for the Broadwell Model

International Journal of Differential Equations, 2016
We consider the existence of nonlinear boundary layers and the typically nonlinear problem of existence of shock profiles for the Broadwell model, which is a simplified discrete velocity model for the Boltzmann equation.

Generalized Boltzmann solution for non-equilibrium flows and the computation of flowfields of binary gas mixture

Propulsion and Power Research, 2012
Hypersonic flows about space vehicles produce flowfields in thermodynamic non-equilibrium with the local Knudsen numbers Kn which may lie in all the three regimes: continuum, transition and rarefied.

Acceleration of Boltzmann Collision Integral Calculation Using Machine Learning

Mathematics, 2021
The Boltzmann equation is essential to the accurate modeling of rarefied gases. Unfortunately, traditional numerical solvers for this equation are too computationally expensive for many practical applications.
