Book excerpt: Numerical simulations and experimental investigations of rising individual Taylor bubble through a vertical sudden expansion and contraction in stagnant Newtonian liquid is presented. The CFD procedure is based on the open source package Gerris which adopts the volume-of-fluid (VOF) method to represent the gas/liquid interface. The numerical method is verified using the existing results of single Taylor bubbles rising in straight columns. The experiments investigate a nitrogen bubble rising in a water-glycerol mixture for different concentrations. The pipe diameter ratio ranges from 0.69 to 1.72. The images of the bubble rising through the singularities are captured by a high-speed camera. Our investigations focus on the transient process of the bubbles passing the singularity. The variations of the bubble velocity and the liquid film thickness are investigated. The results show that the greater expansion ratios yield more perturbations on the bubbles and have strong effects on the tail of the bubble. The unstable bubble tails are cut off into smaller bubbles in some of the test cases and a bubble break-up regime map obtained by simulations has been proposed. The bubble shape variations depend also on the length of the bubbles. For a bubble passing through a contraction, the blocking phenomenon has been observed and a map has been proposed. Finally, this study, based on a large range of Eötvös numbers and expansion/contraction ratios, provides new insights to better understand the effect of singularities on rising Taylor bubbles.

Available in PDF, EPUB and Kindle. Book excerpt: The need to predict, understand, and optimize complex physical and c- mical processes occurring in and around the earth, such as groundwater c- tamination, oil reservoir production, discovering new oil reserves, and ocean hydrodynamics, has been increasingly recognized. Despite their seemingly disparate natures, these geoscience problems have many common mathe- tical and computational characteristics. The techniques used to describe and study them are applicable across a broad range of areas. The study of the above problems through physical experiments, mat- matical theory, and computational techniques requires interdisciplinary col- boration between engineers, mathematicians, computational scientists, and other researchers working in industry, government laboratories, and univ- sities. By bringing together such researchers, meaningful progress can be made in predicting, understanding, and optimizing physical and chemical processes. The International Workshop on Fluid Flow and Transport in Porous - dia was successfully held in Beijing, China, August 2{6, 1999. The aim of this workshop was to bring together applied mathematicians, computational scientists, and engineers working actively in the mathematical and nume- cal treatment of ?uid ?ow and transport in porous media. A broad range of researchers presented papers and discussed both problems and current, state-of-the-art techniques.

Available in PDF, EPUB and Kindle. Book excerpt: Multiphase flows are found in all areas of technology, at all length scales and flow regimes and can involve compressible or incompressible linear or nonlinear, fluids. However, although they are ubiquitous, multiphase flows continue to be one of the most challenging areas of computational mechanics, with numerous problems as yet unsolved. Advanced computational and experimental methods are often required to solve the equations that describe such complex problems. The many challenges that must be faced in solving them include modelling nonlinear fluids, modelling and tracking interfaces, dealing with multiple length scales, characterising phase structures, and treating drop break-up and coalescence. It is important to validate models, which calls for the use of expensive and difficult experimental techniques.This book presents contributions on the latest research in the techniques for solving multiphase flow problems, presented at the seventh in a biennial series of conferences on the subject that began in 2001. Featured topics include: Flow in porous media; Turbulent flow; Multiphase flow simulation; Image processing; Heat transfer; Atomization; Interface behaviour; Oil and gas applications; Experimental measurements; Energy applications; Biological flows; Micro and macro fluids; Compressible flows.

Book excerpt: This book examines the relationship between transport properties and pore structure of porous material. Models of pore structure are presented with a discussion of how such models can be used to predict the transport properties of porous media. Portions of the book are devoted to interpretations of experimental results in this area and directions for future research. Practical applications are given where applicable, and are expected to be useful for a large number of different fields, including reservoir engineering, geology, hydrogeology, soil science, chemical process engineering, biomedical engineering, fuel technology, hydrometallurgy, nuclear reactor technology, and materials science. Presents mechanisms of immiscible and miscible displacement (hydrodynamic dispersion) process in porous media Examines relationships between pore structure and fluid transport Considers approaches to enhanced oil recovery Explores network modeling and perolation theory
