Particle Distribution in an Unbaffled Stirred Vessel by a Novel laser Sheet Image Analysis Technique

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

The availability of experimental information on solid distribution inside stirred tanks is a topic of great importance in several industrial applications. The measurement of solid particle distribution in turbulent multiphase flow is not simple and the development of suitable measurement techniques is still in progress. In this work a novel non-invasive technique for measuring particle concentration fields in solid-liquid systems is presented and employed. The technique makes use of a laser sheet, a high sensitivity digital camera for image acquisition and a Matlab procedure for post-processing the acquired images.Experimental data are here obtained for the case of an unbaffled stirred tank provided with cover. Stable toroidal attractors for particles are observed under given circumstances. Their existence, consistency and extension dependence on particle inertia properties and impeller angular velocity is investigated and discussed.
