RÉSUMÉ
The paper presents large eddy simulations of the flow around a surface-mounted circular cylinder at a Reynolds number of Re = 43000 of height H = 2.5D. In the first part, the different modelling parameters are discussed with respect to their influence on the computed results. One of the findings is that, on the relatively coarse grid employed, the dynamic model is deficient as it yields too large eddy viscosities. The results obtained with the Smagorinsky model are in fairly good agreement with measurements. In the second part of the paper these results are evaluated in detail and related to findings in the literature.
