Sinking Bubbles – On the Behavior of Air Bubbles in a Vertically Oscillating Column of Liquid
We are used to bubbles rising in liquids, however, when a column of liquid is oscillated vertically, it is not always the case. Experiments have been conducted to determine the critical conditions under which such a behavior occurs. In a second part of this paper, it is shown, that the experimental results are in good agreement with an equation of...
