Lattice Boltzmann Thermal Flow Simulation and Measurements of a Modified SAE Model With Heated Plug

This article presents the novel experiment of the modified SAE model with a heated plug and discusses the details about the new developments of the numerical model of the PowerFLOW 4.0 version, which employs a Lattice Boltzmann model and incorporates an improved unsteady two equations RNG k-e turbulence model, a coupled PDE for the energy equation and an advanced wall model for both flow and thermal boundary layers. The hot flow is discussed both experimentally and numerically. Distributions of the flow field are compared with available experimental findings. The predictive capability and the feasibility of the current Lattice Boltzmann approach is demonstrated and the applicability to similar flows over realistic road vehicles is discussed.Copyright © 2006 by ASME
