When a liquid drop impacts a smooth, solid, dry surface, the drop forms a radially spreading lamella, which can lead to a splash. Previous studies have focused almost exclusively on impacts perpendicular to a surface; yet it is common for drops to impact on angled or moving surfaces. The asymmetry of such impacts leads to an azimuthal variation of the ejected rim, and under certain conditions only part of the rim breaks up to form droplets. We show that the tangential component of impact can act to enhance or suppress a splash. We develop a new model to predict when this type of splashing will occur. The model accounts for our observations of the effects of tangential velocity and agrees well with previous experimental data.

- The mechanism of a splash on a dry solid surface (2011, background): “For example, for approximately a 1.7 mm radius ethanol droplet, (5.4) gives a value between 1.25 and 3.75 m s−1, while the experimentally observed value is about 2.4 m s−1 (Range & Feuillebois 1998; Xu et al. 2005; Bird et al. 2009).”
- Review of mass and momentum interactions during drop impact on a liquid film (2016, background): “Even though the splash morphology on a solid surface may seem similar to that on a liquid film, the underlying mechanisms for the two surface targets are fundamentally different [12].”
- Drop Impact on a Solid Surface (2016, unknown): “Bird et al. (2009) additionally showed that the corona-splash can be suppressed on the lamellar stretching side, for a very large translational velocity of the substrate.”
