Book Description
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.
Fluid Mixing II
Author: M.F. EdwardsPublisher: 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.

Author: Hugo A. JakobsenPublisher: Springer Science & Business Media
ISBN: 3540686223
Category : Technology & Engineering
Languages : en
Pages : 1244
Book Description
This book closes the gap between Chemical Reaction Engineering and Fluid Mechanics. It provides the basic theory for momentum, heat and mass transfer in reactive systems. Numerical methods for solving the resulting equations as well as the interplay between physical and numerical modes are discussed. The book is written using the standard terminology of this community. It is intended for researchers and engineers who want to develop their own codes, or who are interested in a deeper insight into commercial CFD codes in order to derive consistent extensions and to overcome "black box" practice. It can also serve as a textbook and reference book.
