Book Description
A new tiechnique has been developed for following the progress of mixing in solid-liquid systems where the solids are less dense than the liquid The technique is based on the measurement of the mass of particles on the liquid surface and uses a monitoring device which consists of a combination of infra-red emitters - detectors to monitor the whole of the liquid surface. The technique offers a number of advantages and reduces the subjectivity usually associated with solid suspension experiments and facilitates the extension of this experiment to any type of vessel. The monitoring device can be calibrated in absolute terms to give the mass of particles on the surface at any time. This allows mixing to be described quantitatively and reproducibly as a function of impeller speed. The experimental work has been carried out in an agitated tank of 140mm diameter for a range of particle concentrations, using disc turbines, 4-bladed 45 degree pitched turbines and a marine propeller. A simple model was developed....

The Mixing Characteristics of Particle-liquid Suspensions in Agitated Tanks
Author: Zong Ming Zhu

ISBN:
Category :
Languages : en
Pages : 189
Book Description
In chemical and process industries, many operations require mixing of solid particles in liquids and are often carried out in mechanically-agitated tanks. This work is an experimental study of particle-liquid mixing at relatively high concentrations by using a matched refractive index method. The method has made it possible to conduct, at high concentrations, particle visualizations with a photographic technique and particle concentration measurement with a light transmission technique. Axial particle concentration profile and uniformity, particle motion pattern, and profile of unsuspended particles have been determined at a given tank scale and impeller size. Effects of impeller speed, impeller clearance, particle size and particle concentration have been examining ed using two impwller typeseller types.....

Fluid Mixing II
Author: M.F. Edwards
Publisher: Elsevier
ISBN: 1483136248
Category : Science
Languages : en
Pages : 213
Book Description
Fluid Mixing II documents the proceedings of a symposium organized by the Yorkshire Branch and the Fluid Mixing Processes Subject Group of the Institution of Chemical Engineers and held at Bradford University, on 3-5 April 1984. The conference covers all aspects of mixing including the assessment of mixture quality, experimental and theoretical studies of mixing, chemical reaction and mass transfer, heat transfer, novel experimental techniques, scale-up and optimization. This volume contains 12 papers that deal with topics such as drawdown of floating solids into mechanically agitated vessels; effects of water/cement ratio, intensity of mixing, age and cement particle size and shape upon rheological properties of cement grouts with and without admixture; and mixing of non-absorbent solids with liquids. Other studies cover the flooding transition of a Rushton turbine operating in a gas-liquid system; power consumption in a three phase (liquid-solid-gas) mixing process in a stirred vessel; and an experimental technique for studying the rate of inter-zone mixing.
