Available in PDF, EPUB and Kindle. Book excerpt: Hydrodynamics in a mixing tanks results from the interaction between the tank geometry and the performance characteristics of the tank internals such as impeller and draft tube. In this book, the standard stirred tank configurations are investigated using both laser Doppler velocimetry (LDV) and computational fluid dynamics (CFD) techniques. The work first focuses on establishing the velocity field in a liquid-only system and then progresses to a solid-liquid system. In the liquid only system, it is shown that a draft tube can be used in a tank stirred by the Rushton turbine, and this improves mixing efficiency and reduces power consumption. For the solid-liquid systems, CFD simulation techniques are developed to determine multiphase mixing features such as cloud height and off-bottom suspension. Poly-disperse multiphase simulation results show the effect of particle size distribution and that of the drag model. The results provide useful information for process optimization and scale up.

This book was released on 2022-10-12 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aerated stirred tank reactors are commonly used for chemical, biological and pharmaceutical processes with the highest requirements for constant and efficient mass transport and mixing performance. These reactors are known for their simple design and a very extensive description of their operating behavior in the relevant literature. The purpose of this work is to identify heterogeneities and coherent structures in aerated stirred tank reactors and to describe what the influences of these structures have on the mass transport and mixing processes. For this purpose, both the global and local mixing time distributions and, for the first time, the dispersion coefficients are determined with high local resolution.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Turbulent Mixing and Chemical Reactions Jerzy Ba???dyga, Warsaw University of Technology, Poland John R. Bourne, Visiting Professor, University of Birmingham, UK and Emeritus Professor, ETH Zurich, Switzerland The way in which reagents are mixed can greatly influence the yield and range of products formed by fast, multiple chemical reactions. Understanding this phenomenon enables chemists to carry out reactions more selectively, make better use of raw materials and simplify product workup and separation. Turbulent Mixing and Chemical Reactions presents a balanced treatment of the connection between mixing and reaction. It contains theoretical aspects, experimental methods and expected results as well as worked examples to illustrate problem solving. This book will be of interest to all scientists involved in chemical engineering, physical chemistry, and synthetic chemists in the fine chemical and pharmaceuticals industry.

Book excerpt: A short review of the state of the art in experimental and computational fluid dynamics (CFD) characterization of micro-hydrodynamics and physicochemical processes in stirred tanks and agglomeration reactors is presented. Results of experimental and computational studies focusing on classical mixing tanks as well as other innovative reactors with various industrial applications are briefly reviewed. The hydrodynamic characterization techniques as well as the influence of the fluid dynamics on the efficiency of the physicochemical processes have been highlighted including some of the limitations of the reported modeling approach and solution strategy. Finally, the need for specialized CFD codes tailored to the specific needs of fluid-particle reactor design and optimization is advocated to advance research in this field.

Available in PDF, EPUB and Kindle. Book excerpt: Traditionally, fluid mixing and the related multiphase contacting processes have always been regarded as an empirical technology. Many aspects of mixing, dispersing and contacting were related to power draw, but understanding of the phenomena was limited or qualitative at the most. In particular during the last decade, however, plant operation targets have tightened and product specifications have become stricter. The public awareness as to safety and environmental hygiene has increased. The drive towards larger degrees of sustainability in the process industries has urged for lower amounts of solvents and for higher yields and higher selectivities in chemical reactors. All this has resulted in a market pull: the need for more detailed insights in flow phenomena and processes and for better verifiable design and operation methods. Developments in miniaturisation of sensors and circuits as well as in computer technology have rendered leaps possible in computer simulation and animation and in measuring and monitoring techniques. This volume encourages a leap forward in the field of mixing by the current, overwhelming wealth of sophisticated measuring and computational techniques. This leap may be made possible by modern instrumentation, signal and data analysis, field reconstruction algorithms, computational modelling techniques and numerical recipes.
