This book was released on 2017 with total page 136 pages. Available in PDF, EPUB and Kindle. 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.

Download or read book Computational Methods for Multiphase Flow written by Andrea Prosperetti and published by Cambridge University Press. This book was released on 2009-06-25 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thanks to high-speed computers and advanced algorithms, the important field of modelling multiphase flows is an area of rapid growth. This one-stop account – now in paperback, with corrections from the first printing – is the ideal way to get to grips with this topic, which has significant applications in industry and nature. Each chapter is written by an acknowledged expert and includes extensive references to current research. All of the chapters are essentially independent and so the book can be used for a range of advanced courses and the self-study of specific topics. No other book covers so many topics related to multiphase flow, and it will therefore be warmly welcomed by researchers and graduate students of the subject across engineering, physics, and applied mathematics.

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.

This book was released on 1990-01-11 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a result of the numerical simulation of multidimensional gas dynamics problems on a computer, the output information is obtained in the form of immense arrays of numerical data. In this connection, there arises the problem of extracting the actually needed information from these arrays; in other words, it is necessary to solve the problem of information compression. In particular, the numerical solution of gas dynamics problems often aims at the information on the solution singularities-the shock waves, contact interfaces, slip lines, etc. Our book is devoted to the development and investigation of accuracy of the algorithms for the localization of such singularities. In addi tion, the questions of development of the algorithms for the classification of singularities into several types (on the basis of shock-capturing numerical solutions of two-dimensional gas dynamics problems) are considered for the first time in the monographic literature. For this purpose, some ideas and methods of the modern theory of digital-image processing and of the pattern recognition theory are used. The information obtained at the output of the systems of the singularities classification presented in this book is rich in content, because it contains both physical and geometrical characteristics of recognized objects. Therefore, such "intellectual" systems of information ex traction may be used in the expert systems of automated design of aero dynamic bodies which meet some optimality requirements. This is, in our opinion, very attractive from the point of view of applications.
