Numerical Simulations of Heat Transfer and Fluid Flow on a Personal Computer


Book Description

This book describes methodologies for performing numerical simulations of transport processes in heat transfer and fluid flow. The reader is guided to make the proper selection of simulation techniques and to interpret the acquired results based on the flow physics involved. Computer programs which are used to solve heat transfer and fluid flow problems are integrated into the text. Illustrative examples of thermo-fluid phenomena are provided in every chapter to enhance understanding of the subjects by offering the reader hands-on experience of numerical simulations. Most of the fundamental transport processes in heat transfer and fluid flow, e.g. heat conduction in a solid body, convection heat transfer of a fin, laminar and turbulent heat transfer and flow in a duct or tube, and boundary layers over a flat plate are covered. A strong emphasis is placed on examinations of the thermo-fluid phenomena inside a flow passage (such as tube and a channel). The book contains detailed discussions on the formulation of the boundary conditions which is often the key issue in making successful numerical simulations of the physical phenomena of interest. Simulations are carefully designed so that conventional 16-bit personal computers, such as IBM PC® or Apple Macintosh® can be used. Visualizing the simulated results in graphic form (plotting charts and line contours of physical variables) significantly enhances the reader's understanding of the important transport processes. The book is intended as an introductory text for numerical simulations of heat transfer and fluid flow phenomena. Description is simple and self-contained so that beginners can easily understand the material, yet it will also serve as a useful reference work for the practitioner. Exercise problems are supplied by which the reader can consolidate knowledge of simulation techniques described and gain further insight in the physical processes of interest. The book contains two 31⁄2 inch floppy disks, each of which stores a complete set of simulation source codes discussed in the text. These programs are recorded in ASCII format and can be run either on IBM PC® or Macintosh® using QuickBasic®. The programs are well-documented within the text as well as in the codes themselves with a number of comment statements. This helps the reader understand the flow of program runs and, if the reader so wishes, modifying the original source codes. To facilitate prescription of the physical conditions for simulations, these programs run in a highly interactive mode. In addition, the diskettes contain a number of compiled programs which can be executed without the QuickBasic® program.

PC-Aided Numerical Heat Transfer and Convective Flow


Book Description

PC-Aided Numerical Heat Transfer and Convective Flow is intended as a graduate course textbook for Mechanical and Chemical Engineering students as well as a reference book for practitioners interested in analytical and numerical treatments in the subject. The book is written so that the reader can use the enclosed diskette, with the aid of a personal computer, to systematically learn both analytical and numerical approaches associated with fluid flow and heat transfer without resorting to complex mathematical treatments. This is the first book that not only describes solution methodologies but also provides complete programs ranging from SOLODE to SAINTS for integration of Navier-Stokes equation. The book covers boundary layer flows to fully elliptic flows, laminar flows to turbulent flows, and free convection to forced convection. The student will learn about convection in porous media, a new field of rapid growth in contemporary heat transfer research. A basic knowledge of fluid mechanics and heat transfer is assumed. It is also assumed that the student knows the basics of Fortran and has access to a personal computer.The material can be presented in a one-semester course or with selective coverage in a seminar.

Performance Optimization of Numerical Simulations of Heat Transfer and Fluid Flow


Book Description

Computational fluid dynamics (CFD) is a branch of fluid mechanics that uses numerical methods to simulate heat transfer and fluid flow phenomena. These numerical simulations require the solution of large linear algebraic systems that arise from the discretization of governing equations and the number of nodes in the discretized mesh is directly related to the accuracy of the simulation. A finer mesh, one with more nodes, will result in better numerical accuracy. However, the computational resources required to solve the linear systems and the overall solution time of the simulation increases with an increased number of nodes. As practitioners continue to develop more complex simulations that require fine meshes, the need for better methods to solve linear systems becomes particularly important. In recent years, there have been significant advancements in computational hardware that have enabled massive parallelism. Multicore processors, graphics processing units, and increased memory capacity have all lead way to significant performance increases for high-performance computing (HPC) workflows that allow for faster and more accurate numerical simulations. However, many of the legacy algorithms used to solve the linear systems in CFD are not well suited to exploit the parallelism in modern computational hardware. Krylov-subspace methods are an ideal solution to this problem as the Krylov algorithms can be parallelized through single-instruction, multiple data (SIMD) operations. In the current study, the Krylov-subspace methods of Bi-Conjugate Gradients, Generalized Minimum Residual, Bi-Conjugate Gradients Stabilized, and Bi-Conjugate Gradients Stabilized (l) are examined as potential algorithms to improve the solution time for numerical simulations of heat transfer and fluid flow. Each of the Krylov methods will be characterized against the standard, line-by-line Tri-Diagonal Matrix Algorithm using a heat conduction model and a Rayleigh-Bénard Convection model. The numerical experiments using heat conduction will examine the impact of grid size and boundary condition placement for each of the algorithms tested. The Rayleigh-Bénard Convection model will be used to determine the performance improvements of the Krylov methods in Patankar's SIMPLER algorithm. The numerical accuracies of each algorithm will be validated using analytical solutions for the heat conduction model and empirical correlations for the Rayleigh-Bénard Convection model.

Numerical Marching Techniques for Fluid Flows with Heat Transfer


Book Description

"It is the purpose of this book to present the finite difference formulation and method of solution for a wide variety of fluid flow problems with associated heat transfer. Only a few direct results from these formulations will be given as examples, since the book is intended primarily to serve as a discussion of the techniques and as a starting point for further investigations; however, the formulations are sufficiently complete that a workable computer program may be written from them."--Page iii
