I am looking for the algorithm of Patankar (for example, SIMPLE, SIMPLER, SIMPLEC and PISO) written in Fortran for the simulation of heat transfer and fluid flow.

Probably the best thing is to use codes from a book by J.Ferziger and M. Peric "Computational Methods for Fluid Dynamics", available from Springer ftp site. site. There you will find F77 codes for 2D Navier-Stokes equations. I suggest starting from 2dc folder and pcol.f code which uses collocated variable arrangement, instead of staggered which was explained in Patankar's book.

Personally I think the Patankar's book appeared three years too early, and it therefore didn't include Finite Volume Method version using collocated variable arrangement enabled after introduction of Rhie-Chow interpolation in 1983. Also Patankar gives a sketch of what is vertex-based median-dual approach, also very important for unstructured meshes, and doesn't go into detail.

I think there is a need for a new book on FVM using general unstructured cells from the start and not using square cells that reduce calculations to something similar to finite differences.

My advice-learn from the codes above, and start reading papers as soon as possible. There are good papers explaining FVM for fluid flows in a comprehensive and modern way.

References that I recommend are:

The list may extend to PhD theses. In OF community H. Jasak's PhD thesis is often cited and is a good reading.

  • $\begingroup$ Thank you very much sir Johntra Volta for all the interest you have given to my question. I think that the book "Computational Methods for Fluid Dynamics" is very interesting for me. But, since I am a beginner in the field of simulation with Fortran 1990, what books can explain how to pass from the theory of FVM for fluid dynamics to the programmation in the Fortran and especially f90 ? Books in the kind of "Numerical Recipes in Fortran 90. The Art of Parallel Scientific Computing. by William H. Press, Saul A. Teukolsky, William T. Vetterling and Brian P. Flannery." $\endgroup$ – simo salah Sep 5 '14 at 1:20

If you still need help, you can refer to this Github https://github.com/xuaoxiqi/Computational-Fluid-Dynamics

It has lid driven cavity flow solved using SIMPLE and is quite explanatory.
