Axisymmetric drop impact dynamics on a wall film of the same liquid
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. 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.
