Abstract:
We compare and discuss measurements and simulations of the flow inside a scour hole around a cylinder mounted vertically in a flume with a sandy bed. The measurements have been performed by stereoscopic particle image velocimetry. For the simulation we have done a highly-resolved large–eddy simulation. This contribution aims to clarify how reliable the simulated results are and which resolutions are needed for a qualitative and quantitative prediction of flow quantities. We demonstrate that for...     »
