This paper deals with numerical simulation of the flow around a 1:5 rectangular cylinder. The Unsteady Reynolds-Aver aged Navier-Stokes (URANS) and Detached-Eddy Simulation (DES) computational 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. These results are further confirmed by the DES method, which provides information about the instantaneous flow variables and offers a deeper insight into the flow physics.
