This book was released on 2021-11-29 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Academic Paper from the year 2021 in the subject Physics - Mechanics, , language: English, abstract: In this study, numerical simulations of a gas-solid fluidized bed reactor involving a two-fluid Eulerian multiphase model and incorporating the Kinetic Theory of Granular Flow (KTGF) for the solids phase have been performed using a commercial Computational Fluid Dynamics (CFD) software. The fluidized bed setup consists of 1,5 m height and 0,2 m diameter in which a series of experiments were performed using Helium tracer to determine the Residence Time Distribution (RTD) at various normalized velocities i.e., with different degrees of gas-solids mixing. Both 2D and 3D simulations of the fluidized bed reactor are performed. The main purpose of this study is to understand the hydrodynamic behavior of a gas-solid fluidized bed reactor through a framework of Eulerian multiphase model and to analyze hydrodynamic behavior of the gas-solids mixing.

Available in PDF, EPUB and Kindle. Book excerpt: A definitive guide for accurate state-of-the-art modelling of free surface flows Understanding the dynamics of free surface flows is the starting point of many environmental studies, impact studies, and waterworks design. Typical applications, once the flows are known, are water quality, dam impact and safety, pollutant control, and sediment transport. These studies used to be done in the past with scale models, but these are now being replaced by numerical simulation performed by software suites called “hydro-informatic systems”. The Telemac system is the leading software package worldwide, and has been developed by Electricité de France and Jean-Michel Hervouet, who is the head and main developer of the Telemac project. Written by a leading authority on Computational Fluid Dynamics, the book aims to provide environmentalists, hydrologists, and engineers using hydro-informatic systems such as Telemac and the finite element method, with the knowledge of the basic principles, capabilities, different hypotheses, and limitations. In particular this book: presents the theory for understanding hydrodynamics through an extensive array of case studies such as tides, tsunamis, storm surges, floods, bores, dam break flood waves, density driven currents, hydraulic jumps, making this a principal reference on the topic gives a detailed examination and analysis of the notorious Malpasset dam failure includes a coherent description of finite elements in shallow water delivers a significant treatment of the state-of-the-art flow modelling techniques using Telemac, developed by Electricité de France provides the fundamental physics and theory of free surface flows to be utilised by courses on environmental flows Hydrodynamics of Free Surface Flows is essential reading for those involved in computational fluid dynamics and environmental impact assessments, as well as hydrologists, and bridge, coastal and dam engineers. Guiding readers from fundamental theory to the more advanced topics in the application of the finite element method and the Telemac System, this book is a key reference for a broad audience of students, lecturers, researchers and consultants, right through to the community of users of hydro-informatics systems.

Available in PDF, EPUB and Kindle. Book excerpt: Useful as a reference for engineers in industry and as an advanced level text for graduate engineering students, Multiphase Flow and Fluidization takes the reader beyond the theoretical to demonstrate how multiphase flow equations can be used to provide applied, practical, predictive solutions to industrial fluidization problems. Written to help advance progress in the emerging science of multiphase flow, this book begins with the development of the conservation laws and moves on through kinetic theory, clarifying many physical concepts (such as particulate viscosity and solids pressure) and introducing the new dependent variable--the volume fraction of the dispersed phase. Exercises at the end of each chapterare provided for further study and lead into applications not covered in the text itself. Treats fluidization as a branch of transport phenomena Demonstrates how to do transient, multidimensional simulation of multiphase processes The first book to apply kinetic theory to flow of particulates Is the only book to discuss numerical stability of multiphase equations and whether or not such equations are well-posed Explains the origin of bubbles and the concept of critical granular flow Presents clearly written exercises at the end of each chapter to facilitate understanding and further study

This book was released on 1998 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this investigation is to numerically predict the effect of an electric field on a two-dimensional gas-solid fluidized bed. The particles in the bed are taken to be of a uniform size and density forming the particulate phase with a gas (air) taken as the continuum phase. A hydrodynamic model of fluidization utilizes the principles of conservation of mass and momentum describing the multiphase flow equations along with the constitutive equations of gas-solid drag and solids stress. A two-dimensional unsteady-state computer code (K-Fix) was used to observe the effect of an electric field on the gas and solid velocities and the void fraction and pressure in the bed. Special case studies included that of a jet, a bubble, and two bubbles, with and without an electric field.

This book was released on 2012-12-06 with total page 737 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computers are widely used for the analysis, design, and operation of water resource projects. This gives accurate results, allowing the analysis of complex systems which may not have been possible otherwise, and the investigation and comparison of several different alternatives in a short time, thereby reducing the project costs, optimizing design, and efficient utilization of resources. This volume compiles an edited version of the lecture notes specially prepared by 14 well-known European and North American researchers. Part I deals with free-surface flows. Governing equations are derived and their solution by the finite-difference, finite-element, and boundary-integral methods are discussed. Then, turbulence models, three-dimensional models, dam-break flow models, sediment transport models, and flood routing models are presented. Part II is related to the modeling of steady and transient pressurized flows. Governing equations for both single and two-component flows are derived and numerical methods for their solution are presented. The modeling of water quality in pipe networks, of cooling water systems, and slow and rapid transients is then discussed.

Download or read book Numerical Simulation Of Pressure Drop In Flow Over Fixed Porous Beds written by Jonathan Olatunbosun and published by . This book was released on 2016-04-20 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bachelor Thesis from the year 2015 in the subject Engineering - Mechanical Engineering, University of Ibadan (Department of Mechanical Engineering), language: English, abstract: The study of porous beds has attracted a wide range of attention in recent years. One issue that has remained standing is that of accurate modelling of the behaviour of pressure drop. This project therefore attempts to add to the existing knowledge in the area by performing a simple numerical simulation of pressure in flow over fixed porous beds. In performing this simulation, the model was governed by two fluid flow principles, the conservation of mass and conservation of momentum using the Brinkman Equations. COMSOL Multiphysics was employed in helping to solve this model because it uses a discretization of finite elements in solving a set of partial differential equations that help to promote accuracy of results. The model involved a rectangular porous bed measuring (25 m x 2 m) for porosity values of 0.2-0.9 at intervals of 0.1 and air and water were used as working fluids. From the simulation performed, the velocity of the porous bed increases for all porosity values by 8.25%. For the range of porosity values between 0.2 and 0.9, the maximum pressure at the inlet of the porous bed was1134.42 Pa. for water and 20.38 Pa for air which occurred at a velocity of 4x10 DEGREES-5 m/s and the minimum pressure at the outlet of the porous bed was 0.045 Pa forwater and 8.16x10 DEGREES-4 Pa for air which occurred at a velocity of 4x10 DEGREES-8 m/s. It can be concluded that a safe range of porosity values in minimizing pressure drop can be found at higher porosity values. This is useful in the design of industrial equipment such as packed bed reactors as
