Multicomponent Flow Modeling
Author: Vincent Giovangigli
Publisher: Springer Science & Business Media
Release Date: 2012-12-06
Pages: 321
ISBN:
Available Language: English, Spanish, And French
EBOOK SYNOPSIS:

The goal of this is book to give a detailed presentation of multicomponent flow models and to investigate the mathematical structure and properties of the resulting system of partial differential equations. These developments are also illustrated by simulating numerically a typical laminar flame. Our aim in the chapters is to treat the general situation of multicomponent flows, taking into account complex chemistry and detailed transport phe nomena. In this book, we have adopted an interdisciplinary approach that en compasses a physical, mathematical, and numerical point of view. In par ticular, the links between molecular models, macroscopic models, mathe matical structure, and mathematical properties are emphasized. We also often mention flame models since combustion is an excellent prototype of multicomponent flow. This book still does not pretend to be a complete survey of existing models and related mathematical results. In particular, many subjects like multi phase-flows , turbulence modeling, specific applications, porous me dia, biological models, or magneto-hydrodynamics are not covered. We rather emphasize the fundamental modeling of multicomponent gaseous flows and the qualitative properties of the resulting systems of partial dif ferential equations. Part of this book was taught at the post-graduate level at the Uni versity of Paris, the University of Versailles, and at Ecole Poly technique in 1998-1999 to students of applied mathematics.

ISBN:
Available Language: English, Spanish, And French
EBOOK SYNOPSIS:

Chemical Reactor Modeling closes the gap between Chemical Reaction Engineering and Fluid Mechanics. The second edition consists of two volumes: Volume 1: Fundamentals. Volume 2: Chemical Engineering Applications In volume 1 most of the fundamental theory is presented. A few numerical model simulation application examples are given to elucidate the link between theory and applications. In volume 2 the chemical reactor equipment to be modeled are described. Several engineering models are introduced and discussed. A survey of the frequently used numerical methods, algorithms and schemes is provided. A few practical engineering applications of the modeling tools are presented and discussed. The working principles of several experimental techniques employed in order to get data for model validation are outlined. The monograph is based on lectures regularly taught in the fourth and fifth years graduate courses in transport phenomena and chemical reactor modeling and in a post graduate course in modern reactor modeling at the Norwegian University of Science and Technology, Department of Chemical Engineering, Trondheim, Norway. The objective of the book is to present the fundamentals of the single-fluid and multi-fluid models for the analysis of single and multiphase reactive flows in chemical reactors with a chemical reactor engineering rather than mathematical bias. Organized into 13 chapters, it combines theoretical aspects and practical applications and covers some of the recent research in several areas of chemical reactor engineering. This book contains a survey of the modern literature in the field of chemical reactor modeling.

Available Language: English, Spanish, And French
EBOOK SYNOPSIS:

Reservoir simulation is an important tool for petroleum engineers to predict oil production andoptimize the management of oil fields. Fluids in oil and gas reservoirs are complex. In many cases,reservoir fluids consist of three or more phases and contain a large number of species that can reactwith each other. Many existing models (black oil, compositional and reactive transport models)were developed to simulate fluids with a specific fluid characterization. In this dissertation, ageneral modeling framework is developed that allows for simulation of different fluid types andprocesses. Based on the general framework we developed a new in-house simulator that we namedPennSim.Reservoir simulators spend over 90% CPU time on the linear solver for reservoir models withover one million grid blocks. The performance of iterative linear solvers depends on the choice ofthe preconditioner, the design of which depends on the knowledge of the PDEs. We designedadvanced multistage preconditioners based on the PDE structure. New decoupling strategies wereproposed for the constraint pressure residual method. Advantageous performance is demonstratedand over three times speed-up is shown.We applied the general modeling framework to design novel models to explore the mechanismsof enhanced oil recovery (EOR). With coupled surface complexation reaction and multiphase flow,we proposed a numerical model for low salinity waterflooding for carbonates. The wettablilityalteration was modeled by detailed description of fluid and surface reactions. Our model is the firstpredictive model for low salinity EOR in carbonates. We also designed the coupled compositionaland reactive model for water-alternating CO2 injection. Injectivity changes were predicted forinjection water with different compositions.This dissertation aims to cover the generic modeling, numerical simulation and fast iterativesolvers for multiphase multicomponent flow and transport in porous media. PennSim wasdeveloped and its manual is available in supplemental materials.
