Essentials of Computational Fluid Dynamics de Jens-Dominik Mueller

Essentials of Computational Fluid Dynamics

Autor Jens-Dominik Mueller
en Limba Engleză Paperback – 6 noi 2015
Covered from the vantage point of a user of a commercial flow package, Essentials of Computational Fluid Dynamics provides the information needed to competently operate a commercial flow solver. This book provides a physical description of fluid flow, outlines the strengths and weaknesses of computational fluid dynamics (CFD), presents the basics of the discretization of the equations, focuses on the understanding of how the flow physics interact with a typical finite-volume discretization, and highlights the approximate nature of CFD. It emphasizes how the physical concepts (mass conservation or momentum balance) are reflected in the CFD solutions while minimizing the required mathematical/numerical background. In addition, it uses cases studies in mechanical/aero and biomedical engineering, includes MATLAB and spreadsheet examples, codes and exercise questions. The book also provides practical demonstrations on core principles and key behaviors and incorporates a wide range of colorful examples of CFD simulations in various fields of engineering.
In addition, this author:
  • Introduces basic discretizations, the linear advection equation, and forward, backward and central differences
  • Proposes a prototype discretization (first-order upwind) implemented in a spreadsheet/MATLAB example that highlights the diffusive character
  • Looks at consistency, truncation error, and order of accuracy
  • Analyzes the truncation error of the forward, backward, central differences using simple Taylor analysis
  • Demonstrates how the of upwinding produces Artificial Viscosity (AV) and its importance for stability
  • Explains how to select boundary conditions based on physical considerations
  • Illustrates these concepts in a number of carefully discussed case studies
Essentials of Computational Fluid Dynamics provides a solid introduction to the basic principles of practical CFD and serves as a resource for students in mechanical or aerospace engineering taking a first CFD course as well as practicing professionals needing a brief, accessible introduction to CFD.

Recenzii

"The book strikes a good balance between practical advice and mathematically oriented explanations. It covers some of the most important real-life CFD topics in depth, such as the issue of turbulence modeling, meshing, or the choice of the boundary conditions."
Marek Behr, RWTH Aachen University, Germany

"Well written and easy to understand. It describes the basic concepts of accuracy, artificial viscosity and stability in a systematic and logical way. Moreover, the introduction of [artificial] viscosity and flux limiters are rarely found or discussed in the other CFD textbooks. This is an excellent textbook to have for students, lecturers and practicing professionals alike. I would like to have this book on my shelf."
Dr. K. Djidjeli, University of Southampton, UK
"This relatively short book is intended for the user of commercial computational fluid dynamics (CFD) packages, as opposed to the developer of such programs. Müeller (Queen Mary Univ. of London, UK) taught CFD to undergraduate students for many years, and he developed the book to accompany a first course on the topic for aerospace or mechanical engineering students. The first eight chapters emphasize the basic physics and the microscopic description of the mathematical equations of fluid mechanics (both laminar and turbulent) and the description and application of finite element mesh modeling of these equations in the vicinity of various geometrical bodies, with appropriate boundary conditions. The sources of errors and the pros and cons of the various turbulent models are also described. Chapter 9 presents several case studies, and chapter 10, the appendix, is a program for a 2-D finite volume application. A short list of exercises follows each chapter. Students will need a solid grounding in basic fluid mechanics and numerical analysis to follow this text."

Descriere

Approaching the material from the viewpoint of a user of a commercial flow package, this book initially limits the description of the mathematics to the level that is strictly needed to make the correct choices when setting up a case in a commercial flow solver. It discusses the sources of errors in FD solutions using simple examples with finite differences, and they are demonstrated with mesh convergence studies. It focuses on the understanding of how the flow physics interact with a typical finite-volume discretization.
