Mixing Time in a Cylindrical Bath Agitated by Gas Injection through a Multi-hole Nozzle

Abstract

Water model experiments were performed to develop a novel agitation method for the desulfurization process. Specifically, we focused on mixing time of a cylindrical bath agitated by gas injection from a multi-hole nozzle. The mixing time was determined by measuring the time-dependent electrical conductivity of a liquid containing a KCl aqueous solution. The mixing time was found to be closely related to the immersion depth of the nozzle. An empirical equation was proposed for the mixing time.
