As a part of an investigation into the nature of imperfect mixing, a study was made of the convective flow in three turbine-stirred, batlled vessels by measuring the response to a pulse of ionic tracer, injected into the impeller zone, with a conductivity cell around the impeller. From these respons

Being the second part of an investigation into the nature of imperfect mixing, this paper discusses the dispersion during the circulation of a tracer pulse, injected into the impeller zone of a turbinestirred vessel. A model of the imperfect mixer is presented, which shows good agreement with the ex
## Abstract An original technique for the determination of the fraction of unsuspended solid particles at agitation speeds smaller than __N__~__js__~, is proposed. The technique is based on the βtwinβsystemsβ concept and is completed by a suitable tracing and detection technique for the solid phase
