Available in PDF, EPUB and Kindle. Book excerpt: 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.....

Available in PDF, EPUB and Kindle. Book excerpt: 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....

Download or read book Fluid Mechanics of Mixing written by R. King and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is a selection of the material presented at the 7th European Mixing Congress. It is concerned exclusively with mixing in circular section vessels, using centrally mounted paddles or similar impellers. The contents are arranged under three classifications: Modelling of Mixing Processes, Mixing Operations and Experimental Techniques. The classifications result in the original material appearing in a different order to that of the Congress. This arrangement is intended to assist the reader in identifying the topic area by function or application, rather than by technology. In this book the section on Modelling contains papers which focus on the representation of the mixing process, whether by equation, scale-up criteria, or fluid dynamic simulation. Similarly, Mixing Operations are concerned with the application or function of the mixing process, such as mass transfer, heat transfer or mixing time. Experimental Techniques addresses the tools the researcher needs to use at the data gathering experimental stage. It collects together advances made in the various methods used by some of the foremost researchers, and indicates those areas still in need of additional instrumentation or methods of data reduction. The book is intended for researchers, designers and users of mixing equipment, and for those planning research and development programmes and who wish to keep up to date with advances in the basic technology and its applications.

Download or read book Engineering Data on Mixing written by Reiji Reiji Mezaki and published by Elsevier. This book was released on 1999-11-19 with total page 781 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a compilation of the engineering data on mixing, which have appeared in the major technical journals of chemical engineering and bioengineering since 1975. That year marked the beginning of a period of rapid advancement in the science and technology of mixing, with rather reliable results for both theoretical and experimental studies. In addition, some important earlier articles which have been, and still are being referred to, are included.Designs of both agitators and tanks still depend primarily on art and experience. In light of this it was felt that the data on mixing should be compiled and presented in a systematic manner to assist in design and analysis of agitated tanks, and to provide easier access to mixing data for various engineering activities. Although computer-aided searches of pertinent data bases can be of assistance to chemical engineers and bioengineers in their studies, they are sometimes time-consuming and often costly. Furthermore inadequate selection of key words can jeopardize the searches. This book offers an alternative method of surveying mixing data which interests readers. The first chapter presents a variety of results for the experimental measurements of flow patterns in stirred tanks. Most of the measurements were made by using modern Laser-Doppler techniques. This chapter is useful for the prediction of flow patterns in tanks with many different geometries, various types of agitators, and fluids of diverse physical and rheological properties, plus valuable data for the validation of results obtained by CFD simulations. Chapters 2 through 5 deal with data for traditional chemical engineering subjects and Chapter 6 summarizes a number of scale-up relations developed over the years for various systems. These include liquid, solid-liquid, liquid-liquid, gas-liquid, and solid-liquid-gas systems. Chapter 7 provides data related to multiphase processes, and most importantly, drop size and drop-size distributions and bubble-size distributions. These two subjects have not been treated systematically either in text books or in handbooks on stirred-tank mixing, although the results of both experimental and theoretical investigations have been reported on many occasions. Finally gas-inducing mechanically agitated systems are dealt with. The applications of this type of agitation system will become increasingly attractive from the standpoint of rationalization of stirred-tank operations as well as environmental protection.

Download or read book Processing of Solid Liquid Suspensions written by P. Ayazi Shamlou and published by Elsevier. This book was released on 2016-08-10 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Processing of Solid-Liquid Suspensions is a collection of articles from several industrialists and academicians who are active in fundamental and applied research relating to handling and processing of particles in liquids. This collection of papers deals with the processes of interaction of particles with each other, with the surrounding liquid and process equipment, whereby knowledge of the mechanism of these interactions can be a sound basis for improving the design of the process equipment and create an optimum environment for the formation and processing of the particulate. The above notion is explained through analysis of the role of turbulent aggregation and breakup of particles in the formation of many solid products from aqueous solutions. This book also analyzes particle size and particulate crystals, whether as final products or as intermediates during processing. In the purification of proteins, two essential units of operation are used; precipitation and solid-liquid separation are analyzed, where theoretical considerations are reviewed. This text also discusses the application of model suspensions in the design of aerobic fermenters in practical industrial uses. High concentration of suspension preparations and solid suspension in liquid flourized beds or in stirred vessels are explained in more detail as to how these affect certain industries. This selection finally presents the progress made in developing design and methods needed by industry. Researchers, chemists, and scientists in industry, as well as advanced students with interests in formation and processing of stable suspensions and in advanced process engineering courses will find this textbook a valuable aid.
