Data from WMLES of a flat-plate TBL using unstructured grids

This dataset accompanies the following publication.<br><b>Mukha, T., Johannson, M., Liefvendahl, M. Effect of wall-stress model and mesh-cell topology on the predictive accuracy of LES of turbulent boundary layer flows. In ECCM-ECFD 2018, Glasgow, UK.</b><br>The dataset consists of simulation data and the two computational meshes the simulations employ.<br>The data is located in the data.zip file. It contains the "VTK" folder that holds full 2D fields of the unknowns, averaged in the spanwise direction. The format is multi-block VTK data, that can be natively read with such software as Paraview and turbulucid.Additionally, several computed quantities are provided as text files. This includes, the skin friction coefficient, the wall shear stress and others. The naming convenction is that Paved and Poly corresponds to data from simulations on the paved and polyhedral grids, respectively. And 1st and 3rd refers to the location of the sampling point of the WMLES mesh.<br><br>The meshes.tar file contains the two meshes -- paved and polyhedral -- which are stored in OpenFOAM format.<br><br>For more information about the simulations, refer to the article. Please cite it, if you use the data.<pre><br></pre>
