WitrynaConsequently, assessment of impact jetting at planetary scales has been largely based on the theories developed for such specific types of collisions. Little experimental work has been done, however, to measure both temperature and target-to-projectile mass ratio of jetting created by spherical projectiles impacting planar targets, which typify 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. Witrynainitial impact force is of interest as it can damage the solid.
