canonical problem is influenced by many physical parameters, including projectile …

Impact on granular beds

D Van Der Meer - Annual review of fluid mechanics, 2017 - annualreviews.org
The impact of an object on a granular solid is an ubiquitous phenomenon in nature, the

Maximal air bubble entrainment at liquid-drop impact

W Bouwhuis, RCA van der Veen, T Tran, DL Keij… - Physical review …, 2012 - APS
At impact of a liquid drop on a solid surface, an air bubble can be entrapped. Here, we show
that two competing effects minimize the (relative) size of this entrained air bubble: for large …

Cavity dynamics in the oblique water entry of a cylinder at constant velocity

Y Hong, Z Zhao, Z Gong, H Liu - Physics of Fluids, 2022 - pubs.aip.org
Transient cavity dynamics in the oblique water entry of a cylinder at a constant velocity is
investigated. The drag force exerted on the cylinder is measured by a force sensor, and the …

Highly focused supersonic microjets
