Excel files with experimental results for moderate and high impact velocity are available for download through the website https://tudatalib.ulb.tu-darmstadt.de/handle/tudatalib/3295 or via the following doi: https://doi.org/10.48328/tudatalib-722. Besides the experimental results, the Excel files also include results of numerical simulations with a phase-field method employing different spatial resolutions of the diffuse interface (indicated by ''N''<sub>c</sub>) and models for the surface tension force (equilibrium/relaxation), see Figure 4. A detailed discussion on the experimental and numerical results is given in the following publication:

Excel files with experimental results for moderate and high impact velocity are available for download through the website https://tudatalib.ulb.tu-darmstadt.de/handle/tudatalib/3295 or via the following doi: https://doi.org/10.48328/tudatalib-722. Besides the experimental results, the Excel files also include results of numerical simulations with a phase-field method employing different spatial resolutions of the diffuse interface (indicated by Nc) and models for the surface tension force (equilibrium/relaxation), see Figure 4.
