Binary Gas Thermal Conductivity Questions
Binary Gas Thermal Conductivity Questions
(OP)
I would like to understand if thermal conductivity is linear between a differing helium% / air% binary gas mixture and also how it changes at varying pressures between 1atm to 10atm. See below image:

RE: Binary Gas Thermal Conductivity Questions
If you had two pure gases then it would be linear and you could use ideal gas corrections for pressure.
If there is moisture in your air then it would throw things off a little bit.

RE: Binary Gas Thermal Conductivity Questions
For your pressure range, the thermal conductivity only increases by about 1% per atm.
There's no simple approach like a mol or mass weighted average and you'd need to reach the section to figure out how to apply it and hopefully find an example to work through. Any chance someone where you works have a copy of this book? This was one of my University textbooks so a few people might have a copy.
$37.25. And I thought they were expensive back then.

I really appreciate your help. We are looking to use helium or a combination of helium/air at pressure to cool some parts coming out of a heat treat oven.

We cannot quench in a liquid. Other suggestions?
