You can modify rhoCentralFoam to add steger-warming fluxes. Thats what I did here

http://gfoam.svn.sourceforge.net/

though I have not added that particular flux.

Hiiii Praveen , thanks for your reply but i am currently working on openfoam 2.00 version. By seeing your link i am totally confused. Is it possible to send me some reference code (related to flux vector splitting) that u had done. It will really help me a lot. My mail id dushyantbajaj1984@gmail.com

Thanks & Regards
Dushyant

Hiiii nimasam
Thanks for showing your interest -- I had written a implicit code in c for the steger warming splitting . Now i want to add this scheme in OpenFoam as existing one like rhocentralfoam. So i need to know the process of doing it. I understood the oblique shock reflection problem solved using rhoCentralfoam but now i dnt know how to add my scheme and test this problem.
