Cylinder-wall junction flow
Underlying Flow Regime 3-35
This study follows a dual approach using a numerical as well as an experimental approach. We applied a highly resolved large eddy simulation as well as a particle image velocity experiment to the flow around a cylinder mounted vertically on a flat rigid plate. Both data sets refer to the same set-up, but were acquired independently and are made accessible in files at the end of the Evaluation section of this document. The data for the inflow condition can be found at the end of the Test Case Studies section of this document, too.
In general, the numerical and experimental results do agree with each other. However, slight deviations are visible such as for the time-averaged position of the vortex system. To ease the comparison of the velocity profiles at the same positions relative to the vortex system, we introduced an adjusted horizontal coordinate. The data presented below were evaluated at distinct horizontal positions in this adjusted coordinate system and are thus located at the same positions relative to the vortex in both numerical and experimental datasets.
