Data from wall-modelled LES of channel flow and flow over a backward-facing step

This dataset accompanies the following article<br>T. Mukha, S. Rezaeiravesh, M. Liefvendahl, A library for wall-modelled large-eddy simulation based on OpenFOAM technology, Computer Physics Communications, 2019,DOI: 10.1016/j.cpc.2019.01.016<br>The contents of the archive are simulation cases the results from which are presented in the paper. This includes WMLES of turbulent channel flow and the flow over a backward-facing step (BFS). For all the simulations, a full OpenFOAM case, including initial condition fields, is provided. <br><br>The following conventions apply- The number at the beginning of the case's name refers to the density of the gird n/delta.<br>- h1 and h2 refer to sampling from the wall-adjacent and second off-wall cell.<br>- linear and lust correspond to using the respective schemes for discretising the convective term.<br>- For all cases, the grid can be constructed using blockMesh<br>- For channel flow cases, the profiles directory holds averaged data. For completeness even moments that should be zero are included.<br>- For the BFS, the fields averaged in time and the spanwise direction are held in the average.vtm file. This can be opened with Paraview, turbulucid or other VTK-based software.<i><br></i><i>Note: </i>the backflow field in the BFS cases actually holds the probability of forward-flow.<br>The correspondence between the directory structure of the archive and the sections of the article should be straight-forward to understand.<br><br>Note, the BFS cases require generating inflow fields. The precursor simulations that can be used for this purpose are included in the archive. To convert the generated surface-samples into a single hdf5 file we recommend using the Python package eddylicious, seehttp://eddylicious.readthedocs.iofor documentation and guidelines for using with OpenFOAM.<br><br><br><br><br>
