Witrynasphere of radius R. While the solid sphere is an extended object, we will assume that the projectile is a point-like mass. In this case, it is clear that if the incoming projectile has an impact parameter larger than R, it will not be de ected at all, while if the impact parameter is less than R, it may su er a relatively extreme de ection.

Witryna28 sty 2024 · To identify the mechanism responsible for the liquid jetting, we can follow in more detail the dynamics of the liquid impacting on the solid surface in Fig. 6. As the particle rises through the drop, the liquid separates from the solid particle to impact on the solid surface around a circle of similar size as the particle ( = 0.22). WitrynaWe use a novel ultra-high-speed video camera to study the initial stage of the impact of a solid sphere onto a liquid surface, finding a high-speed horizontal jet which emerges immediately following the intial contact. For Re > 2 x 10(4) the jet emerges when the horizontal contact between the sphere and the liquid is only 12% of its diameter.
