SIMPLE method for 2-D flow
 

Dear Sirs, I'm developing a program to simulate a compressible flow within a 2-Dimensional impulse blade cascade using SIMPLE method. Please, can you guide me to the suitable CFD code that is free or low cost (just a simple 2-D flow simulation for an academic research). This could help me to check out and validate my own work, also if any one know the location of any site offering such service so one can give his data and give him run then please inform me as soon as possible.

Thank you very much in advance for your help and understanding, your earliest reply will be highly appreciated.
