The purpose of this paper is to describe some of the technology behind the Lattice Boltzmann approach to exterior airflow simulations as incorporated into the commercial CFD code, PowerFLOW®. The fundamental approach used is the Lattice Boltzmann Method (LBM) coupled with both a turbulence model to recover the dissipation of sub-grid eddy scales and a wall model to allow reduced resolution in the near-wall region. A description of LBM and both models is given. Comparisons to methods that directly solve the Navier-Stokes equations, such as finite volume or finite element methods (hereafter, collectively referred to as RANS methods) are also presented.A demonstration of the technology is presented by comparing numerical simulations with extensive experimental test data on Ford's standard calibration models. These models were originally described in SAE paper 940323 [1].
