Book excerpt: Mass transfer from single rising gas bubbles is generally studied by taking motion pictures of the rising bubbles and analyzing the film for the instantaneous mass transfer coefficient. In this study, a different approach was taken for the analysis of mass transfer. This analysis solved the simultaneous differential equations describing mass transfer by numerical techniques. The computer model developed is restricted to pure single gas bubbles in water, with diameters in the size range 0.01 ≤ diameter ≤ 0.30 cm. Given a bubble's initial diameter and height of water over the bubble, the model predicts the bubble's position and moles of gas present in the bubble at any other time. The bubble rise velocity was calculated by considering a force balance on a spherical bubble and used theoretical values of drag coefficients based on a sphere. Correlations presented by Hamerton and Garner, Frossling, and Weiner were used to solve for KL, the convective mass transfer coefficient. The time dependent behavior of KL, attributed to the accumulation of surface active agents at the rising bubble's interface, was accounted for by the development of a bubble age parameter, termed critical time. The differential equations were solved by a Runge-Kutta-Merson routine, and the model applied to a carbon dioxide-water system. The results were compared to data collected in the investigations of Deindoerfer, Garbarini, and Datta. The computer predictions, with the inclusion of the critical time parameter, corresponded closely to data presented by the three investigators. The model, without the critical time parameter, predicted mass transfer rates much higher than those presented in the three investigations. The model was extended to pure oxygen-water and air-water systems to aid in the modeling of gas dispersion equipment used in aeration ponds. Predictions indicate that the initial bubble diameter has a significant role on the overall mass transfer.
Download or read book A Computer Model of Two Component Mass Transfer from Single Rising Gas Bubbles in Water written by Thomas L. Gilson and published by . This book was released on 1985 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mass transfer from a single rising gas bubble in water may be analyzed by numerical methods. In this study the simultaneous differen- tial equations which describe two component mass transfer from a rising gas bubble are solved by numerical integration. This is accomplished using a computer model which employs a Runga-Kutta-Merson routine. Given the depth and diameter of an orifice, and the initial composition of the bubble the computer model will predict the bubble's depth, diameter, composition, and the total number of moles present in the bubble at any time. The bubble may contain up to two water soluble components and one inert component and should be restricted to the range 0.01 cm

This book was released on 2011-03-10 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Accurately predicting the behaviour of multiphase flows is a problem of immense industrial and scientific interest. Modern computers can now study the dynamics in great detail and these simulations yield unprecedented insight. This book provides a comprehensive introduction to direct numerical simulations of multiphase flows for researchers and graduate students. After a brief overview of the context and history the authors review the governing equations. A particular emphasis is placed on the 'one-fluid' formulation where a single set of equations is used to describe the entire flow field and interface terms are included as singularity distributions. Several applications are discussed, showing how direct numerical simulations have helped researchers advance both our understanding and our ability to make predictions. The final chapter gives an overview of recent studies of flows with relatively complex physics, such as mass transfer and chemical reactions, solidification and boiling, and includes extensive references to current work.

Book excerpt: This book is devoted to a fundamental understanding of the fluid dynamic nature of a bubble wake, more specifically the primary wake, in liquids and liquid-solid suspensions, an dto the role it plays in various important flow phenomena of multiphase systems. Examples of these phenomena are liquid/solids mixing, bubble coalescence and disintergration, particle entrainment to the freeboard, and bed contraction.

Available in PDF, EPUB and Kindle. Book excerpt: This volume offers a critical review of the literature concerning the fluid dynamics, heat transfer, and mass transfer of single bubbles, drops, and particles. Upper-level undergraduates and graduate students, as well as professionals in the fields of engineering, physics, chemistry, geophysics, and applied mathematics, will find it a unified treatment of solid particles, liquid drops, and gas bubbles. Starting with a summary of the fundamental principles and equations governing the behavior of bubbles, drops, and solid particles in Newtonian fluids, the text proceeds to a survey of the parameters used to characterize the shape of rigid particles, and of the factors that determine the shape of bubbles and drops. Succeeding chapters examine the behavior of solid and fluid particles under steady incompressible flow in an extended external phase. The text concludes with an exploration of effects that complicate the relatively simple case of a particle moving steadily through an unbounded fluid.

Available in PDF, EPUB and Kindle. Book excerpt: From the Authors' Preface The advancements of technology . . . and chemical engineering have brought about extensive use of a wide range of rheologically complex materials, e.g., polymeric solutions and melts, suspensions, mixtures, oil products, fibre-forming substances, etc. that are characterized by diverse and, every so often, significant deviations from classical Newtonian behavior. Such materials are often used in conditions where the formation of vapor-gas bubbles or two-phase flow regimes is possible. This necessitates deep investigations into the thermo-hydrodynamic problems of liquids with bubbles for the case of a continuous phase with anomalous rheological properties. These conditions are typical of a number of applications and manufacturing processes, e.g., gas removal from polymeric solutions or melts in production of film, chemical fibres and other polymeric materials. . . . The bubbles containing gas or vapor-gas mixtures are often present in polymeric systems. This is because of a number of reasons, e.g., a low wettability of solid surfaces by polymers, the use of volatile solvents, abundance of vapor-gas nuclei, the capture of gas by porous or fibre-like polymeric particles during the polymer dissolution or melting, etc. Spontaneous evacuation of bubbles in polymeric media is usually complicated by a high viscosity of the liquid; therefore two-phase polymeric systems possess a higher sedimentation and aggregation stability than bubble mixtures in low-molecular-weight liquids. One of the main problems in the dynamics of vapor-liquid and gas-liquid systems is the investigation of heat and mass transfer and phase interactions in a liquid with bubbles. The decisive importance of this problem in the analysis of various aspects of the bubbly fluid behavior under diverse conditions, in particular, during a sound wave propagation, has given impetus to numerous researches. The current state of art in the investigation of Newtonian liquids with bubbles is described in voluminous literature. However, these problems have been much less studied for non-Newtonian systems. Behavior of bubbles in polymeric liquids is of great interest because of wide application in chemical technology. . . . In a number of processes connected with the application of polymeric fluids, the dynamic interaction of bubbles with liquid phase plays the key role. Such interaction in the case of a polymeric liquid phase are essentially influenced by the specific properties of macromolecular fluids, including primarily the rheological effects. These effects in the bubble dynamics combined with heat and mass transfer between the bubble content and the ambient liquid constitute the main subject of the analysis presented in this book.
