Towards Development of a Multiphase Simulation Model Using Lattice Boltzmann Method (LBM)
Lattice Boltzmann Method is evolving as a substitute to the prevalent and predominant CFD modeling especially in cases such as multiphase flows, porous media flows and micro flows. This study is aimed at developing simulation model for multiphase flows for practical applications such as cavitation in a journal bearing or lubrication of micro contact. The code is first validated against benchmark single phase flows like Poiseulle flow and flow over a cylinder. In the process, various boundary conditions like velocity, pressure, out-flow, no-slip and periodic boundary conditions are tested. Finally, the Shan-Chen model for multiphase physics, which is based on the interaction force between the fluid particles, is incorporated into the code and is validated.
Multiphase Lattice Boltzmann Methods
Theory and Application of Multiphase Lattice Boltzmann Methods presents a comprehensive review of all popular multiphase Lattice Boltzmann Methods developed thus far and is aimed at researchers and practitioners within relevant Earth Science disciplines as well as Petroleum, Chemical, Mechanical and Geological Engineering. Clearly structured throughout, this book will be an invaluable reference on the current state of all popular multiphase Lattice Boltzmann Methods (LBMs). The advantages and disadvantages of each model are presented in an accessible manner to enable the reader to choose the model most suitable for the problems they are interested in. The book is targeted at graduate students and researchers who plan to investigate multiphase flows using LBMs. Throughout the text most of the popular multiphase LBMs are analyzed both theoretically and through numerical simulation. The authors present many of the mathematical derivations of the models in greater detail than is currently found in the existing literature. The approach to understanding and classifying the various models is principally based on simulation compared against analytical and observational results and discovery of undesirable terms in the derived macroscopic equations and sometimes their correction. A repository of FORTRAN codes for multiphase LBM models is also provided.
Numerical Simulation of Multiphase Reactors with Continuous Liquid Phase
Numerical simulation of multiphase reactors with continuous liquid phase provides current research and findings in multiphase problems, which will assist researchers and engineers to advance this field. This is an ideal reference book for readers who are interested in design and scale-up of multiphase reactors and crystallizers, and using mathematical model and numerical simulation as tools. Yang and Mao's book focuses on modeling and numerical applications directly in the chemical, petrochemical, and hydrometallurgical industries, rather than theories of multiphase flow. The content will help you to solve reacting flow problems and/or system design/optimization problems. The fundamentals and principles of flow and mass transfer in multiphase reactors with continuous liquid phase are covered, which will aid the reader's understanding of multiphase reaction engineering. - Provides practical applications for using multiphase stirred tanks, reactors, and microreactors, with detailed explanation of investigation methods - Presents the most recent research efforts in this highly active field on multiphase reactors and crystallizers - Covers mathematical models, numerical methods and experimental techniques for multiphase flow and mass transfer in reactors and crystallizers
