Comprehensive reviews on the drop impact onto a solid substrates wetted by a thin film can be found in Yarin (2006), Liang & Mudawar (2016) and Yarin, Roisman & Tropea (2017).

Experiments on the dynamics of the droplet-wall-film interaction in the event that the entire impact process is rotational symmetrical are lacking so far. Such data are highly relevant for the development of simulation methods, since the numerical effort of axisymmetric computations remains limited compared to 3D calculations and extensive comparative studies can be carried out for validation and methodical developments. The present experiment provides such data and has been especially designed for the validation of CFD methods for numerical simulation of two-phase flows where the gas-liquid interface is well resolved.
