Hi Guys,

I know this is a bit naive of me but I'm currently reading the CFD book "An Introduction to Computational Fluid Dynamics" by Versteeg and Malalasekera.

So far I've read up to page 70 but I'm still confused as to what's happening. The equations are just overwhelming and the overall theory is just really hard to understand and complex. I'm reluctant to read more into the book since I don't think it will be useful considering I don't understand the fist couple of chapters.

Can anyone provide any suggestions or book alternatives for CFD beginners like me?

Thanks

If you find a Taylor' series expansion overwhelming, hard to understand and complex, then a moment of sincerity is due, look your science, math back ground,
Take any undergraduate level textbook about Numerical Analysis, read the chapters about the solution techniques of ordinary differential equations, partial differential equations, matrix solution methods, then come back to this introductory text.
The book by Anderson is also introductory to cfd, may be the style suits you, but if you want to be comfortable reading any of these two books, study Numerical analysis First
Wish you success and Good Luck

I use An Introduction to Computational Fluid Dynamics by Versteeg and Malalasekera in teaching a graduate CFD course. Chapters 2 and 3 (pp 9-114) can be somewhat overwhelming as they present material on the differential equations of fluid dynamics and a discussion of turbulence. These topics are important for understanding the theory of the equations that CFD codes are solving.

If you can accept that CFD is solving partial differential equations and that turbulent flows need models, you can start at Chapter 4 with a discussion of numerical analysis. This will give you some more information about the C of CFD; you can then return later to the FD part.

The chapter on turbulence (where you got stuck at page 90) has some material that can be difficult to understand on turbulent fluctuations. However, it is important to skim this chapter for the sections that advise you on what turbulence models are appropriate for what flow situations. This includes a discussion of what boundary conditions to use and how your choices of boundary conditions and grid size are related.
