Investigation of Drop Size in Liquid-Liquid Dispersion Agitated by Sawtooth Impeller: Effect of Optical Measuring Device

Abstract

Experimental measurement of drop size in immiscible liquid-liquid dispersion using non-disruptive in-situ non-invasive method utilizing high-speed image capturing and Image Analysis strongly depends on the quality of captured images. This contribution aims to analyze the effect of optical properties of the image acquisition system on the determination of the drop size in a baffled vessel agitated by a high-shear sawtooth impeller. The experiments were carried out for three impeller speeds at low dispersed phase volume fraction when the drop breakage occurs only.
