Capillary Wave and Initial Spreading Velocity at Impact of Drop onto a Surface

Autor: P. F. Li, S. F. Wang, W. L. Dong

Publikováno v: Journal of Applied Fluid Mechanics, Vol 12, Iss 4, Pp 1265-1272 (2019)

The capillary wave and initial spreading velocity in the spreading phase of drop impacting on a glass surface are studied experimentally, while the drop photos are obtained by using a high-speed video camera, which can catch up to 9000 images per sec
