Abstract
This paper deals with the numerical simulation of the flow around a 1:5 rectangular cylinder and a realistic bridge section. The Unsteady Reynolds-Averaged Navier-Stokes (URANS) and the Detached-Eddy Simulation (DES) techniques are employed. In the process the influence of various modelling parameters, such as turbulence modelling, and flow parameters, such as Reynolds number and incidence angle, is investigated. Simulations with both stationary and harmonically oscillating body are performed. Validation of computed results with experimental data shows that the URANS-based computational approach is capable of predicting the basic unsteady flow phenomena in the considered cases, although it is affected by some obvious limits. It seems possible to better understand and overcome these limits with the DES approach.
