Abstract

Provide a summary of the test-case submission here.

The normal impact of a single drop onto a thin wall film of the same liquid is characterized using a high-speed shadowgraphy. The initial kinetic energy of the drop is chosen to meet two requirement. First, it is sufficiently high to give rise to the formation of a notable crown. Second, it is sufficiently low to avoid disintegration of the crown rim (splashing). The entire dynamics of the droplet-wall film interaction is laminar and rotational symmetric. This makes the data set especially useful for advancement and validation of interface-resolving numerical methods for two-phase flows. To this end, high quality time-resolved experimental data on three characteristic dimensions of the crown are provided for two different impact velocities.
