Hello, 

I am trying to simulate air dissociation effect in hypersonic flow. I import Chemkin mechanism into Fluent. For the thermodynamic data, when I just use two temperature ranges, it works fine, the two temperature range format is as followings:

However when I tried to use three temperature ranges:

Fluent gives me Error: Invalid THERMO data at line no. 18.n.

I checked the "Chemkin-Pro Input Manual", it says "using more than two temperature ranges", the format should be like this. Is it that Fluent does not support more than two temperature ranges?

Could someone help me here?

Thank you,

Qing

Hello! Are there anyone who can help me with my question?

It seems that after changing from "ANSYS customer portal support" to this "student community", it becomes quite difficult to get support from ANSYS support engineers.

Which mechanism are you trying to use?

[kzqing]

I use my own defined mechanism. It looks like this:

REACTIONS

O2+M<=>2O+M                              3.610E+18   -1.000  117968.40

   REV/ 3.01E+15    -0.500    0.00/

O2/ 9.00/ N2/2.00/ O/ 25.00/ N/ 1.00/ NO/ 1.00/ 

.....

end

 

Thanks,

Qinq
