Oscillation Behavior of Water Droplets on Solid Surfaces Available to Purchase

An experimental investigation was conducted to describe the oscillation behavior of water droplets on solid surfaces as air flew through over the droplets, and the dynamical process was recorded using a high-speed CCD. Two liquid drop oscillation modes, forward-backward and upward-downward, and their mutual conversion were visually observed. Accounting for the internal flow and pressure distribution inside a liquid drop, a phenomenological explanation was proposed to understand the oscillation characteristics of two modes and the mutual conversion mechanisms.
