摘要：

We study experimentally the impact of solid spheres in a viscous liquid at moderate Reynolds numbers (Re similar to 5-100). We first determine the drag force by following the slowdown dynamics of projectiles. We then focus on the shape of the free surface: such impacts generate cavities, whose original shape is described and modeled. (C) 2013 American Institute of Physics.
