Is there a simple NS or Euler solver?

Hello, everyone!
I am learning the finite volume method currently. After reading some books and papers, I am going to write a small solver with the purpose to make a good understanding of fvm.
After some attempts, I found it hard to create the whole Ns or Euler eq and also met some other complicated problems.
At last, I think I should start from some open source. So, I am wondering is there any open source of simplest fvm code easy to read and understand for beginners? Both fortran and c/c++ are acceptable.
Any advice will be highly appreciated!
Thanks!

Try NSC2KE it is an open source NS code (Fortran 77 if I remember correctly).

It is not finite volume, but for simplicity look at the first 2D LDC code on the CFD-Wiki->source code archive->educational. For what it does, the thermal cavity code is pretty simple too.

Thanks all, I will try them.

I have solved NS equation in serial of 6 papers, below is first one, the second will be published soon.
Please,help me, put this information in forum.
I am bad programmer and cannot do it myself.

Does a physically reasonable solution of the Navier
Stokes equations exist?

I think this online "Journal of Engineering and Technology Research" may be one to avoid.
