The file contains the supporting data for the thesis "Large-eddy Simulation of Flow and Pollutant Dispersion behind a Heavy-duty Vehicle". In the thesis, flow behaviors were examined first to improve the understanding of vehicular wake dynamics with the large-eddy simulation (LES) method. Our LES results were validated by comparing them with wind-tunnel experimental results from a previous study. The comparison result is contained in the "Validation" folder. The analysis of flow and pollutant dispersion is...
