A detailed Computational Fluid Dynamics (CFD) study of the flow around a Computer Simulated Person (CSP) in an otherwise empty displacement ventilated room is presented. Both Reynolds Averaged Navier-Stokes (RANS) and Large Eddy Simulation (LES) methods are included in this study. The study identifies the requirements of several computational aspects that are needed for accurate CFD simulations of the personal micro-environment, which include issues related to grid size and iterative convergence monitoring, turbulence modeling, and radiation modeling. Using the benchmark test for evaluating CFD in the indoor environment of Nielsen et al. (2003), very good agreement between CFD results and test data was obtained using the standard ?-e with wall treatment and a reduced-order radiation model.
