Axisymmetric drop impact dynamics on a wall film of the same liquid
Abstract
Provide a summary of the test-case submission here.
The dynamics of the normal impact of a single drop onto a thin wall film of the same liquid is characterized using high-speed shadowgraphy. The initial kinetic energy of the drop is chosen to meet two requirement. It is sufficiently high to give rise to the formation of a notable crown and sufficiently low to avoid any disintegration of the crown. Thus, splashing is avoided and the entire dynamics of the drop-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, time-resolved experimental data on three characteristic dimensions of the crown are provided for two different impact velocities.
