Measurement data/results
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. The content of the Excel files is described below.
In the numerical simulations, two different models for the surface tension force (equilibrium/relaxation) are employed in combination with different spatial resolutions. The latter is quantified by the number of mesh cells Nc used to resolve the diffuse interface as illustrated in Fig. 6.
Fig. 7 compares experimental results for the three crown dimensions with numerical results obtained for the two surface tension models and different grid resolution.
A more detailed discussion on the experimental and numerical results is given in the following publication:
