Radiation coefficients Argon
 

Hello!

I am working on a model with an operating pressure of 300 000 Pa and a temperature of 1000 K in the walls that are in contact with the gas, which is Argon.

I have set up the emissivity of the walls, but when it comes to the absoption and scattering coefficients of the gas, I am completely lost.

I have been searching in the internet for hours, but the only things I found are:

-Calculator, but I am not sure about the units.
-Argon is not a greenhouse gas because it is almost totally unaffected by infrared radiation


Can anybody tell me anything about the topic? Can I neglect the absortion and scattering of Argon??


Thank you very much!
