Hello, in my research, i would like to be able to calculate the thermal conductivity of the following gases at high température: nitrogen (N2), oxygène (O2), carbon dioxide (CO2) and water vapour (H2O). please, is there law/formula to get the thermal conductivity of these gases?
thank you
Dear Ulrich Nzemo Nketcha,
For N2 you can use the following links.

For O2, I have attached one article.
For all type of gases you can verify the following link which the mathematical equation has been introduced. https://www.thermopedia.com/content/1186/#:~:text=For%20the%20model%20of%20gas,of%20unit%20of%20mass%20at
Dear Mina :
I'm not sure of the exact answer but maybe i can give you a clue.
For N2 and O2 look for the Einstein's model of the Specific Heat of substances, at high temperatures.
I don't know what is the range of temperatures you are looking for, but in general, for high temperatures, if I remember well, the Einstein model of c (specific heat) for these di-atomic gases have little deviations from the experimental models you can find in literature
Been able to determine the Specific Heat of substances will lead you straightforward to the information of the Thermal Conductivity.
Best Regards !
