High-speed video data for settling of dense liquid droplets through liquid media with different viscosities

Overview

This data article presents a high-speed video dataset of dense liquid droplets settling through liquid media with different viscosities. The dataset was generated to support experimental and numerical studies of multiphase flow and droplet dynamics.

The data provides reference material for validation of numerical models and analysis of droplet behaviour under controlled laboratory conditions.

Abstract

A dataset of high-speed video footage of mercury droplets settling through liquid media of different viscosities is presented. Video footage was taken at 4000 frames per second for mercury droplets at room temperature settling through either deionised water or silicone oil. The data set is useful for validation of computational models of a wide range of systems which include phase separation studies, settling behaviour as well as interfacial phenomena in liquid-liquid systems. The data can serve as an analogue for validation for fluid systems where dimensional similarity exists and experimentation is not possible due to hostile experimental conditions, e.g. settling of molten metal through molten oxide slag in pyrometallurgical furnaces
