注水上游污染

Upstream contamination in water pouring

S. Bianchini, A. Lage-castellanos, E. Altshuler

摘要:

我们报告的观察上游运输的漂浮颗粒时,清水倒在一个平坦的水面上的伴侣或白垩颗粒喷洒的表面。因此,原本仅位于下部容器表面的颗粒可能会通过“骑”在涡流水流上而污染上部水源。我们推测,Marangoni力与几何诱导的旋涡相结合,可以解释所观察到的现象。

英文摘要:

We report the observation of upstream transport of floating particles when clear water is poured on the surface of a flat water surface on which mate or chalk particles are sprinkled. As a result, particles originally located only at the surface of the lower container can contaminate the upper water source by "riding" on vorticial water currents. We speculate that Marangoni forces in combination with geometry-induced vortices may explain the observed phenomenon.
