This dataset contains the numerical data of the Marangoni convection test case from the study "Visual Analysis of Interface Deformation in Multiphase Flow". In the two investigated scenarios, a water drop coalesce with an ethanol drop. In one case, solutocapillary driven flow phenomena are taken into account, whereas in case to these phenomena are neglected.<br> The simulations were performed by using the multiphase flow CFD solver Free Surface 3D (FS3D) by the Institute of Aerospace Thermodynamics (ITLR) <br>

Text:

The marangoni.tar file contains two folders for the simulations which take solutocapillary convection into account (with-marangoni) and which do not (without-marangoni). Both folders contain the following files: fs3d.xmf (timeline of the hdf files, contains the data structure), netz_xyz.hdf (grid corner points), funsXXXX.hdf (volume fractions of liquid phase f), velvXXXX.hdf (velocity field (u,v,w)), sigmXXXX.hdf (field of the surface tension coefficient sigma). The folder with-maranongi contains additionally the following files: do_xXXXX.hdf (gradient of the surface tension coefficient in x-direction), do_yXXXX.hdf (gradient of the surface tension coefficient in y-direction), do_zXXXX.hd (gradient of the surface tension coefficient in z-direction). For both cases 19 time steps have been written out (XXXX --> 0000-0019).
