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.

Available in PDF, EPUB and Kindle. Book excerpt: In conjunction with the work on interfacial area and contact time, an investigation was carried out to study the factors affecting mass transfer coefficients in vapor-liquid contacting. Measurements of point efficiency on the distillation of a systems of acetone and water determined both the liquid and vapor mass transfer coefficients under various operating conditions. The study was conducted on a 4" diameter column using the same type of single-slotted 1.5" diameter cap employed in the previous work. The range of physical properties and operating variables included: vapor rate: G=5000 to 25,000 lbs./sq.ft.(hr.); liquid rate: L=500 to 3,600 lbs./sq.ft.(hr.) ; vapor Reynolds number: 6400 to 24,100; liquid Reynolds number: 35 to 800 ; vapor Schmidt number: 0.27 to 0.42; liquid Schmidt number: 50 to 330. Both vapor and liquid mass transfer coefficients were correlated as "jD" factors, with their respective Reynolds numbers. The equations developed were: [....]. In combination with the results on interfacial area and contact time, a generalized correlation for point efficiency data reported in the literature (30,53) and found it to be in excellent agreement. Based upon analysis of this and other studies reported in the literature (21,22) an explanation of the mechanisms involved in bubble plate mass transfer operations was presented. Since the efficiencies measured in this study were uniformly high, even in the absence of a froth zone, it was indicated that a substantial portion of the mass transfer occurring on a bubble cap plate takes place in the bubble formation region.

Available in PDF, EPUB and Kindle. Book excerpt: The field of multiphase flows has grown by leaps and bounds in the last thirty years and is now regarded as a major discipline. Engineering applications, products and processes with particles, bubbles and drops have consistently grown in number and importance. An increasing number of conferences, scientific fora and archived journals are dedicated to the dissemination of information on flow, heat and mass transfer of fluids with particles, bubbles and drops. Numerical computations and "thought experiments" have supplemented most physical experiments and a great deal of the product design and testing processes. The literature on computational fluid dynamics with particles, bubbles and drops has grown at an exponential rate, giving rise to new results, theories and better understanding of the transport processes with particles, bubbles and drops. This book captures and summarizes all these advances in a unified, succinct and pedagogical way. Contents: Fundamental Equations and Characteristics of Particles, Bubbles and Drops; Low Reynolds Number Flows; High Reynolds Number Flows; Non-Spherical Particles, Bubbles and Drops; Effects of Rotation, Shear and Boundaries; Effects of Turbulence; Electro-Kinetic, Thermo-Kinetic and Porosity Effects; Effects of Higher Concentration and Collisions; Molecular and Statistical Modeling; Numerical Methods-CFD. Key Features Summarizes the recent important results in the theory of transport processes of fluids with particles, bubbles and drops Presents the results in a unified and succinct way Contains more than 600 references where an interested reader may find details of the results Makes connections from all theories and results to physical and engineering applications Readership: Researchers, practicing engineers and physicists that deal with any aspects of Multiphase Flows. It will also be of interest to academics and researchers in the general fields of mechanical and chemical engineering.
