| Abstract | In the present paper the three-dimensional flow fields around three different wall-mounted cylinder stump geometries are evaluated. A combined approach which uses experimental as well as numerical investigations is applied to provide an extensive data base. The ability to compare measured and computed data increases the reliability of the deduced conclusions. For the experimental investigations laserDoppler anemometry is used to determine the average velocity vectors and the RMS-values of the velocities. Concerning computational fluid dynamics three different simulation techniques are applied. A shear stress transport (SST) turbulence model represents RANS approaches. A hybrid simulation technique combining Reynolds averaged Navier-Stokes (RANS) and large eddy simulation (LES) features is realized by the scale adaptive simulation (SAS) model. The third type of numerical simulation is a large eddy simulation (LES), that is able to capture the unsteady flow field in the entire computational domain. Experimental and numerical results are presented and compared with each other. |
