This book covers the essentials of fluid mechanics and explains how to apply fundamental principles to achieve optimum time and capacity efficiency with a minimum of waste. Individual chapters are devoted to the mixing tank, power consumption in turbulent flow, power consumption in viscous creeping flow, mixing in turbulent agitated tanks, and laminar mixing and gas dispersion in agitated tanks. The book provides guidelines for performing design calculations, determining design limits and validating design methodology. The book also covers safety considerations and scale-up processes, and includes technical references to assist the validation of design equations.

Mixing: Theory and Practice, Volume III is a five-chapter text that covers the significant improvements in the theoretical aspects and knowledge in mixing related to industrial-scale operations. The introductory chapters deal with the agitation of particulate solid-liquid mixtures and the turbulent radial mixing in pipes, with particular emphasis on the effects of jets and baffles on such mixing. The following chapter presents the theoretical analysis and experimental confirmation for predicting hydrodynamic characteristics and some process results in mechanically agitated vessels. Another chapter provides a comprehensive development of approaches and recommended practices for scale-up of agitated liquid equipment. The methods considered serve as a useful guide for reducing the risk of scale-up and scale-down catastrophes. The last chapter discusses the fundamental concepts and measures of the quality of mixing and the mechanisms of mixing and segregation. This chapter also introduces the process of continuous mixing of solids.

Two mixing time models, including a circulation model, are tested, using a selection of mechanical impellers. Only the circulation model is found to fit the data. The circulation model is adapted to incorporate mixing in an air-agitated tank. A comparison between air and mechanical agitation seems possible in terms of the circulation model.

Gas-liquid mass transfer, agitator power consumption, rheology, gas-liquid mixing and gas hold-up have been studied in an agitated, sparged vessel of diameter, T = 0.3 m, with a liquid capacity of 0.02 m\(^3\), unaerated liquid height = 0.3 m. The solutions of sodium carboxymethylcellulose used exhibit moderate viscoelasticity and shear thinning behaviour, obeying the power law over the range of shear rates studied. The gas-liquid mass transfer was studied using a steady state technique. This involves monitoring the gas and liquid phase oxygen concentrations when a microorganism (yeast) is cultured in the solutions of interest. Agitator power consumption was measured using strain gauges mounted on the impeller shaft. Various agitator geometries were used. These were: Rushton turbines (D = T/3 and D = T/2), used singly and in pairs; Intermig impellers (D = 0.58T), used as a pair; and a 45° pitched blade turbine (D = T/2), used in combination with a Rushton turbine. Gas hold-up and gas-liquid flow patterns were visually observed. In addition, the state of the culture variables, (oxygen uptake rate and carbon dioxide production rate), were used to provide a respiratory quotient, the value of which can be linked to the degree of gas-liquid mixing in the vessel. Measurement of point values of the liquid phase oxygen concentration is also used to indicate the degree of liquid mixing attained. The volumetric mass transfer coefficient, k\(_L\)a, was found to be dependent on the conditions in which the yeast was cultivated, as well as being a function of time. These variations were associated with variations in solution composition seen over the course of each experiment. Steps were taken to ensure that further k\(_L\)a values were measured under identical conditions of the culture variables, in order to determine the effect on k\(_L\)a of varying viscosity, agitator speed and type and air flow rate. Increasing solution viscosity results in poorer gas-liquid mixing and.

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.
