transonic airfoil
 
Hi...
I have four questions, answer them separately please:
1: I am looking a free fortran code to generate an structured grid over an airfoil (the airfoil coordinates will be imported to the code), is it not the waste of time looking for it on the web? anybody can help me?

2:Anybody can help me by introducing a website that i can find the discretised spallart allmaras turbulence model ? if not anybody can help me in descretising it by finite volume method? do you know any source code that is using this model as its turbulence model?

3:how can i find the descretised navier stokes equations to simulate a transonic flow over a given airfoil???

4: is there anything else to model a flow over an airfoil???

For the transonic regime you can use any commercial CFD code in order to calculate the flow over your airfoil (Fluent for e.g.).

Also you can check NSC2KE which is a NS code implemented in Fortran, however the code uses the K-epsilon turbulence model and not SA. The code is open source so you have a chance to see an actual implementation.

If you are familiar with C++ you can also check OpenFoam.

why ???? what is the reason i can not use a code to simulate the transonic regime?

i can not find this code NSC2KE
could you please send it to me?

Check this link:

http://pauillac.inria.fr/cdrom_a_gra...nsc2ke/eng.htm

You will also find on the same page the documentation for the code in Postscript format.
