Axisymmetric drop impact dynamics on a wall film of the same liquid
Abstract
Provide a summary of the test-case submission here.
High quality time-resolved experimental data for the normal impact of a single drop onto a thin wall film of the same liquid are provided. 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 vecocities.
