Exploring a new dimension in high-speed liquid-liquid impact —Radu Cimpeanu (Warwick) & Matthew Moore (Oxford)

Direct numerical simulation (various angles in a composite image) of a water drop of diameter 1 mm impacting onto a deep liquid pool at a 45 degree angle of incidence with an initial velocity of 10 m/s. The liquid-liquid interfaces are coloured using the norm of the velocity field. The underlying (adaptive) volume-of-fluid discretisation is also highlighted.
