how can model two different gas in shock tube?
 

hi
How can define two gases like air and co2 in both sides of shock tube

The two gas mixture
 

Hi, I meet with the same problem with you. So I wander if you have solved this problem? Thanks in advance

Hi dear Wenfu
I didn't do that because i changed to put a passive scalar in my main case.:D
but you can use reactingFoam( and possibly some of other combustion solvers).
I'm interested in still (although not need anymore).
please let me now when you had any progress and/or think I can help to do such thing together.really I say I'm ready and still interested in doing it together.:)
maybe it be a good start selecting a shock tube problem tutorial from compressible tutorials and on the other hand modify it by reactingFoam tutorials(most in thermophysicalProperties file)
-------------------------------------------
also anyone interested please help us!

hi
if you solve this problem, can you explain to me

Two years later, and I have the same question.
Any suggestions?
