Student Guide
to CFD
Volume 3

    Hoffmann, Dietiker

Return to Book List

This three-volume text, “student Guide for CFD,” is designed to accompany the three-volume text “computational Fluid Dynamics,” by Hoffmann and Chiang.  In order to assure continuity, identical chapter numbers are used in this text as in “Computational Fluid Dynamics,” where a prefix of SG is added in this text.  Furthermore, when the same equation, previously identified in “Computational Fluid Dynamics”, appears in this text, it is identified based on the previous designation.  Numeration of any other equation will include the prefix of SG.  It is noted that chapters in the text “Computational Fluid Dynamics” which do not require computer code development will not be included in this text.  The emphasis in this text will be on the Reynolds Averaged Navier-Stokes equations with several turbulence models, corresponding to Chapter 21 of the text “Computational Fluid Dynamics – Volume III.”  Therefore, the text “Student Guide for CFD – Volume III includes chapters SG21 and SG22.          

It is important to emphasize that computer code development is an important aspect of CFD, and, in fact, one learns a great deal about the numerical schemes and their behavior as one develops, debugs, and validates his or her own computer code.  Therefore, it s important to state here that the computer codes provided in this text should not be used as an avenue to replace that aspect of CFD, and code development must be an important objective of the learning process.  With this goal in mind, then, this text is developed with the intention of facilitating the achievement of this objective.  That is, the codes provided in this text can be used as a basis upon which one may develop other codes, or the codes provided here can be modified for other applications.          

It is also very important to emphasize that the codes developed in this text are not all-purpose codes and should not be viewed as such.  That would be obviously a daunting and expensive task and well beyond the objectives set here.  Furthermore, the computer programs are written in either FORTRAN77 or FORTRAN90 and are executed with an Absoft Pro Fortan compiler.  Depending on the particular FORTRAN compiler used, some modifications in the computer programs will be required.  The computer programs provided in the accompanying diskette are written to run of PC’s.  IF workstations or mainframe computer are used, then system-dependent and compiler-specific parameters may require modifications.
