Validation of a Lattice-Boltzmann Approach for Transonic and Supersonic Flow Simulations

Abstract

A novel three-dimensional Lattice-Boltzmann Method (LBM) based approach for compressible flow in the transonic and supersonic flow regime is validated against theoretical and experimental findings for fundamental flows. The basic equations of the 39state Lattice-Boltzmann for mass and momentum conservation are briefly outlined. Validation results demonstrate the capability of the current Lattice-Boltzmann approach to accurately capture shocks and reproduce the complex flow structure in transonic flows. The method can easily handle very complex geometries and simulate unsteady flow phenomena.
