The paper presents the numerical results obtained with the use of the FLUENT commercial code for analysing the flow structure around a single cube and two rectangular inline surface-mounted bluff bodies immersed in a boundary layer. In the former case, clear effects of the inflow boundary layer thickness on the wall-shear stress within the wake of a single body are described. In the latter case, the grid resolution accuracy in predicting periodic vortex shedding from two tandem arrangement bodies is examined. Moreover, the aim of this study is to highlight the differences between steady and unsteady simulations.
