Abstract
The present paper describes the dynamics of a drop as it falls through a stratified fluid with two layers. As it enters the fluid, the drop forms an annular vortex that suffers different deformation processes depending on the conditions of the experiment. In this work, the only variables that have been modified are the density of the drop and the height of the upper fluid. Images of the phenomena were taken directly with a high speed video camera and through a shadowgraph set-up. To access the videos of the experiment, a http address and a QR image are provided at the end of the paper.
