This study presents an experimental and numerical investigation on the impact morphology and the onset of splashing for the interaction of a hexadecane drop with a thin wall-film of the same liquid. Experiments were carried out for Weber numbers between 300 and 1400 and a dimensionless film thickness between 0.1 and 0.5. The experimental and numerical setups are briefly outlined. The uncertainty of the experimental results is analyzed carefully. In agreement with previous studies, the impact morphology is mapped and divided into the three classes of splashing, deposition, and transition. However, two additional phenomena, the formation of a jet and a bubble, are observed. Their occurrence is not sporadic, rather it reproduces systematically both in one-component and binary systems. Since bubble and jet formation are observed in this study, the only unique impact feature for two-component interactions is the formation of holes inside the crown wall. For the splashing/deposition limit an empirical correlation, based on the K-factor, is proposed and compared to available splashing limits in literature. Taking into account the experimental error, all three splashing limits are in good agreement with the experimental results. Furthermore, the applicability of the in-house code FS3D for the computation of the impact morphology and splashing/deposition limit for one-component droplet wall-film interactions is demonstrated.
