Air chemistry

August 23, 2002, 01:29

Hello CFX users,

I want to ask all the CFX users whether CFX has the capability to simulate air chemistry (non equilibrium). Has anybody come across such application and tried to solve with CFX.

Thanks in advance,

Can you explain what 'air chemistry' is?

When air is at high temperatures its dissociation takes place and different species like NO,No2 etc etc are formed. At even higher temperatures (around 9000K) ionisation takes place. This is reffered to as air chemistry. I hope I have made it clear....

Thankx for the interest

Anyways, I have found that CFX as of now does not has the air chemistry incorporated in it. Further comments are invited.

Actually, people do flows with chemistry all the time with CFX. You could do this in CFX-4 and possibly CFX-5. You only need to enter the reaction mechanism.
