Abstract

The European Research Community on Flow, Turbulence and Combustion (ERCOFTAC) in collaboration with the EU-Network Project QNET-CFD have established a knowledge base wiki accessible via http://qnet-ercoftac.cfms.org. uk in order to provide reliable CFD test cases and corresponding guidelines for solving the individual flow problems. For establishing quality and trust in CFD, experimental and numerical data on a wide range of flows are placed at the disposal of the fluid mechanics community. It includes application challenges for individual industrial sectors and more generic flows. For the latter detailed experimental data as well as highly resolved numerical simulations are available. The objective of the present contribution is to report on a new generic test case which has been recently added to the data base. The results presented are based on the one hand on experimental investigations using particle image velocimetry and on the other hand on numerical predictions relying on direct numerical simulations and large-eddy simulations with two independent codes. After presenting some of the data available, hints and guidelines for the appropriate prediction of this flow case are given.
