Derivation and analysis of Lattice Boltzmann schemes for the linearized Euler equations

摘要

We derive Lattice Boltzmann (LBM) schemes to solve the Linearized Euler Equations in 1D, 2D, and 3D with the future goal of coupling them to an LBM scheme for Navier Stokes Equations and a Finite Volume scheme for Linearized Euler Equations. The derivation uses the analytical Maxwellian in a BGK model. In this way, we are able to obtain second-order schemes. In addition, we perform an L-2-stability analysis. Numerical results validate the approach. (C) 2015 Elsevier Ltd. All rights reserved.
