Abstract
Compared with other variations of drop impacts, the oblique impact has received comparatively little attention.
Most experimental work detailed in the literature has focused on the perpendicular impact while subsequently vary-
ing other parameters. Indeed, it has been theorized that an oblique impact behaves much like a perpendicular impact
except with the perpendicular component of the velocity being applicable to the behavior. But an oblique splashing
drop preferentially splashes in the direction of travel (component parallel to the surface). Very little information
exists to help describe how angled drop impacts differ from the perpendicular impacts. Motivation to better under-
stand large-scale impacts has led to increased concern regarding these phenomena. Resources have been invested in
experiments and modeling efforts to better describe the oblique splash problem.
