 July 13, 2001, 21:48 Your help needed #1 Rafaqat Ullah Guest   Posts: n/a i am an aerospace graduate from Kingston University london. My Degree only had a couple of modules of aerodynamics in it. However, Aerodynamics and CFD, both subjects fascinate me. I am planning to apply for Msc CFd in 2002, at cranfield university. Now what i want, is to develope a strong background in CFd before starting the course..as i have a year out to learn stuff in my free time. People here in the forum are obviously intelligent and well developed in CFD field, so i want on your advice on how to go about developing my knowledge. What books are good for beginners ??? any reccomended software ?? online tutorials ???? My interests do lie in the aerospace field though. Any help from anyone here will be much appreciated. Thanx in advance.

 July 14, 2001, 10:29 Re: Your help needed #3 dia Guest   Posts: n/a have a look to this book; Riemann Solvers and Numerical Methods for Fluid Dynamics Springer-Verlag. Second Edition, June 1999, 624 pages. E. F. Toro (author).

 July 15, 2001, 03:19 Re: Your help needed #4 John C. Chien Guest   Posts: n/a (1). CFD by my definition is "Numerical Analysis and Mathematical Modeling in Fluid Mechanics". (2). So, the most difficult part is "the numerical analysis" and "the turbulence modeling". (3). If you can study these two subjects thoroughly, you will in good shape. (4). To write a program and solve a problem, you normally pick only one scheme and one model. So, there is no need to learn every method and model available. (5). It takes time to learn these two subjects, so focus your time and effort there. (6). To solve a problem is quite simple after you have these basic skill, it is just like : define your problem, create geometry and mesh, apply the boundary conditions, select the numerical scheme and turbulence model, write the code to solve the system of algebraic system, get converged solutions. That's all.

Anderson: Computational Fluid Dynamics, McGraw-Hill, a very good intrduction book, talks about: - Finite Difference - Accuracy - Stability => the basics you have to know working with CFD (2) M Griebel, T. Dornseifer, T. Neunhoeffer: Numerical Simulation in Fluid Dynamics, SIAM - based on the implementation of the code - 2D - Finite Differneces - Implementation in C - very good description of the matter - you can run you first "basic solver (lid driven cavity, backward facing step, cannal flow)" within 4 weeks of intensive programming => this book helped me very much, I strongly recomment it

 July 30, 2001, 22:32 Re: Your help needed #7 clifford bradford Guest   Posts: n/a Try also the books by (1) Tannehill, Anderson, and Pletcher and (2) Culbert Laney (Computational Gasdynamics) (3) Hirsch (the classic reference). The CFD books list on CFD-Online is good too and will have the names of all these books. My approach to self teaching CFD is to take a book (say one of the three above) go through it as much as possible and get a hold of some of the more significant reference articles (the most interesting, the parts you don't understand etc) you'll probably need access to a good engineering library. Good luck Cranfield is a good school

 August 20, 2001, 06:01 Re: Your help needed #9 C.Bhasker Guest   Posts: n/a Steps outlined in the John C Chien is turns to be followed different approach, if one considers to real 3d flow with multiphysics and multi dome geometry. Full utilisation of commerical packages like CFX-TASCflow, CFX-4, Star-CD, fluent and Phoenics and repeated runs for optimisation of components provides tangible benefits to design engineers. Howerever, skills for usagae of cad softwares for geometrical modelling and grid generation varies from person to person. Leaving these trends, going to writing codes for 2D and single domain 3D flow problems for prediction of viscous turbulent flow is still a time consuming and to the restricted usage.
