    In this study, two turbulent flow simulation methods, unsteady Reynolds-averaged Navier-Stokes (URANS) simulation and implicit large eddy simulation (ILES), were compared to resolve separated flow around a high-rise building at 1:1:2 shape. In the URANS analysis, a second-order accurate finite volume method with the κ - ω SST turbulence model was applied. In the ILES analysis, a third-order accurate flux reconstruction method, on the other hand, was adopted. Time-averaged velocity profiles at various positions were compared with the wind-tunnel experiment. It was found that both approaches can successfully resolve incoming boundary layer. However, the URANS did not capture the velocity profiles on the roof as well as behind the building well. The ILES gave a relatively closer velocity profile to the wind tunnel result for those regions due to better resolution of wake turbulent structures. Time-averaged streamlines around the building were also presented to compare overall flow structures.
