Evaluation of the lattice boltzmann method using palabos on benchmark flows

Abstract

This project provides a description of the Lattice Boltzmann Method (LBM), an alternate numerical method to conventional CFD methods. For its promising potential, LBM has grown in favor within the scientific community in recent years. It claims to reach the same degree of accuracy as classical CFD while also providing new benefits such as easy parallelization and the ability to perform complex and multiscale flows. Unlike conventional CFD, which works on the numerical solution of the Navier Stokes Equations, the Lattice Boltzmann Method focuses on microscopic particle interactions to reflect the macroscopic behavior of the fluid. The objectives of this paper is to evaluate and analyze the Lattice Boltzmann Method's capacity to accurately simulate incompressible flows. This study describes the theoretical foundations of this novel method, as well as a CFD simulation of classical configurations. These configurations are developed using modified Palabos codes, with an emphasis on matching LBM solutions with analytical or existing solutions. The results and analyses suggest that LBM is a reliable method for modelling incompressible flows. The study also discusses how to use the Lattice Boltzmann Method and suggests strategies to continue the research.
