EXP 1-4 Measurement Data and Results
Axisymmetric drop impact dynamics on a wall film of the same liquid
Measurement data/results
Provide files of the measurement data together with format information/read-me files. Some graphical presentation of the results should also be given like profiles along characteristic lines or contours in characteristic planes of mean and if possible turbulence quantities, streamlines, etc. and the so presented results should also be discussed briefly.
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.
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 modeling of the surface tension force (equilibrium/relaxation), see Figure 4. A detailed discussion on the experimental and numerical results is given in the following publication:
