Download or read book Hydrodynamics and Mixing in Stirred Tanks written by Ochieng Aoyi and published by LAP Lambert Academic Publishing. This book was released on 2009-11 with total page 196 pages. 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.

Book excerpt: Biotechnology is an expansive field incorporating expertise in both the life science and engineering disciplines. In biotechnology, the scientist is concerned with developing the most favourable biocatalysts, while the engineer is directed towards process performance, defining conditions and strategies that will maximize the production potential of the biocatalyst. Increasingly, the synergistic effect of the contributions of engineering and life sciences is recognised as key to the translation of new bioproducts from the laboratory bench to commercial bioprocess. Fundamental to the successful realization of the bioprocess is a need for process engineers and life scientists competent in evaluating biological systems from a cross-disciplinary viewpoint. Bioprocess engineering aims to generate core competencies through an understanding of the complementary biotechnology disciplines and their interdependence, and an appreciation of the challenges associated with the application of engineering principles in a life science context. Initial chapters focus on the microbiology, biochemistry and molecular biology that underpin biocatalyst potential for product accumulation. The following chapters develop kinetic and mass transfer principles that quantify optimum process performance and scale up. The text is wide in scope, relating to bioprocesses using bacterial, fungal and enzymic biocatalysts, batch, fed-batch and continuous strategies and free and immobilised configurations. - Details the application of chemical engineering principles for the development, design, operation and scale up of bioprocesses - Details the knowledge in microbiology, biochemistry and molecular biology relevant to bioprocess design, operation and scale up - Discusses the significance of these life sciences in defining optimum bioprocess performance

Abstract: Abstract of the thesis entitled A NUMERICAL STUDY OF COUPLED NONLINEAR SCHRODINGER EQUATIONS ARISING IN HYDRODYNAMICS AND OPTICS submitted by Suk-Chong TSANG for the degree of Master of Philosophy at the University of Hong Kong in June 2003 This thesis reports the findings of numerical studies of coupled nonlinear Schrodinger equations (CNLS) in both hydrodynamics and optics applications, and its focus was a model for interaction between wavepackets in the framework of CNLS. Generally, group velocity dispersion, self-phase modulation and cross-phase modulation terms are present in these equations. However, intermodal dispersion and linear coupling terms may also exist when CNLS are applied in optics. The interplay between these effects plays a crucial role in pulse evolution. A numerical method, the Hopscotch method, was introduced to solve CNLS. This is a particularly simple method for solving CNLS, and its accuracy was verified by ascertaining the evolution of a single soliton solution of CNLS and comparing this numerical solution with the exact solution. Two applications of CNLS were studied, in hydrodynamics and optics respectively. In hydrodynamics, CNLS is used to govern the interaction of wavepackets in layered fluid. The long-time evolution of periodic solution of CNLS iwas studied. The initial phase difference, amplitude ratio between perturbations and the ratio between the self-phase and cross-phase modulations were found to be important factors in long-time evolution. Different patterns of evolution may result from different combinations of these three effects mentioned above. In optics, CNLS can be used as the governing equation for wavepackets in directional couplers. Soliton interaction in directional couplers was studied, as their performance can be quite different from how they behave in single-mode fibers. Their behaviour was influenced by group-velocity dispersion, intermodal dispersion and linear coupling terms within the equations. Group-velocity dispersion was found to cause pulse coalescence, and intermodal dispersion was the cause of pulse splitting. The effect of group-velocity dispersion depends on the initial separation between the two input pulses. The closer the two pulses are located, the larger the effect on each other; but there will always be intermodal dispersion effect, no matter how far the pulses are separated. The findings of this study contribute to an increased understanding of the roles of different terms within a CNLS. The interplay between these terms can result in different patterns of evolution. ii DOI: 10.5353/th_b2665265 Subjects: Schrodinger equation Hydrodynamics - Mathematical models Optics - Mathematical models
