Multiphysics Modeling Series – serie

Fins have been used historically as reliable design features for thermal management, which continues to be an important problem in engineering today. This book develops heat transfer models for progressively complex fin designs. Mathematicians, engineers, and analysts may equally benefit from the content as it provides the reader with numerical and analytical tools to approach general and thermal management heat transfer problems. The main focus is on the COMSOL® Multiphysics Heat Transfer module; however, the fundamentals may be applied to other commercial packages such as ANSYS and Abaqus. The content can be utilized in a variety of engineering disciplines including mechanical, aerospace, biomedical, chemical, civil, and electrical, etc.

Features:

Includes numerous example models that enable the reader to implement conceptual material in practical scenarios with broad industrial applications Uses COMSOL Multiphysics® version 5.3 in combination with the Heat Transfer Module to set up and carry out the numerical analysis for the models presented in the book Presents mathematical methods related to the problems Includes a companion disc with models and custom apps created with COMSOL Application Builder (available by emailing info @ merclearning.com with proof of purchase if e-version)

This book focuses on the geometry creation techniques for use in finite element analysis. Examples are provided as a sequence of fin designs with progressively increasing complexity. A fin was selected as it is a feature widely employed for thermal management. As the content progresses, the reader learns to create or import a geometry into a FEM tool using COMSOL Multiphysics®. The fundamentals may also be applied to other commercial packages such as ANSYS® or AbaqusTM. The content can be utilized in a variety of engineering disciplines including mechanical, aerospace, biomedical, chemical, civil, and electrical. The book provides an overview of the tools available to create and interact with the geometry. It also takes a broader look on the world of geometry, showing how geometry is a fundamental part of nature and how it is interconnected with the world around us.

Features:

Includes example models that enable the reader to implement conceptual material in practical scenarios with broad industrial applications Provides geometry modeling examples created with built in features of COMSOL Multiphysics® v. 5.4 or imported from other dedicated CAD tools Presents meshing examples and provides practical advice on mesh generation Includes companion files with models and custom applications created with COMSOL Multiphysics® Application Builder.

Designed for use by the professional engineer or in a senior level course, Multiphysics Modeling Using COMSOL v.4 explores a wide range of models in coordinate systems from 1D to 3D and introduces the readers to the numerical analysis techniques employed in the COMSOL Multiphysics® software.

This book can be used as a reference for the topic of turbulence modeling, especially in an engineering modeling and simulation course or as a tool for professionals on practical applications. Turbulent flow modeling has many applications in industry. The relevant numerical methods have advanced to the level that could be used by industry professionals to model many natural turbulent flows with acceptable accuracy. In this book we cover the fundamentals of turbulence, modeling techniques, and algorithms (including RANS) available in COMSOL® as well as providing several modeling examples and instructions for building these models. The companion DVD includes models and figures discussed in the book.eBook Customers: Companion files are available for downloading with order number/proof of purchase by writing to the publisher at info@merclearning.com.

Features:

Includes companion DVD with models and figures discussed in the book Explains the physics and principles of turbulence and provides modeling examples using COMSOL

COMSOL Multiphysics software is one of the most valuable software modeling tools for engineers and scientists. This book is designed for engineers from the fields of mechanical, electrical, and civil disciplines, and introduces multiphysics modeling techniques and examples accompanied by practical applications using COMSOL 4.x. The book includes a companion CD-ROM with files of over 25 models, images, and code. The main objective is to introduce readers to use COMSOL as an engineering tool for modeling by solving examples that could become a guide for modeling similar or more complicated problems. The objective is to provide a collection of examples and modeling guidelines through which readers can build their own models. Readers are assumed to be familiar with the principles of numerical modeling and the finite element method (FEM). The book takes a flexible-level approach for presenting the materials along with using practical examples. The mathematical fundamentals, engineering principles, and design criteria are presented as integral parts of examples. At the end of each chapter are references that contain more in-depth physics, technical information, and data; these are referred to throughout the book and used in the examples. COMSOL for Engineers could be used to complement another text that provides background training in engineering computations and methods. Examples provided in this book should be considered as "lessons" for which background physics could be explained in more detail.
