Specific heat polynomial for air(default by FLUENT)

Panboy · September 17, 2013, 04:39

hi CFD community,

When I use a polynomial for specific heat of air, a default polynomail shows that has 2 equations: one for 100-1000 K, and another for 1000K to 3000K.
I am trying to find out where FLUENT found this polynomial. Does anyone know?

I know Gordon and McBride has a pretty popular polynomial for separate species, but I looked into their article and they did not have one just for air.

Just seeing where I can reference this polynomial. Thanks!

Hi Panboy,

Did you find it out? I'm trapped in the same question.

Hi Panboy,

Did you figure this out? I'm looking for the same information. The fluent user guide points to four references. I doubt it's this one "J.W. Rose and J. R. Cooper, editors. Technical Data on Fuels. Wiley, 7th edition. 1977." But I don't have access to this book. Thank you!
