In this study, detached eddy simulation (DES) based on a modification to the Spalart-Allmaras one equation RANS model is applied to predict aerodynamic characteristics of the flow around a box girder bridge.Single and tandem types of box girder cross sections are treated.One-equation RANS model and LES based on the Smagorinsky model are also used for the same simulation.The improved balancing tensor diff-usivity (IBTD) / fractional step (FS) finite element formulation is applied to a computational procedure.Comparing with results of wind tunnel test and other turbulence models, the applicability of DES is examined and the aerodynamic characteristics of each cross section are also discussed.
