thermochemical properties format
 

Hi, Does anyone give me, any information about Gordon-McBride format?

And where can I find any proprieties of new materials(web address)? Regards Mohamed

Thank for your help.

I look a website, but I note

that the forme for the fits is

Cp/R= a_1*T^-2 + a_2*T^-1 + a_3 + a_4*T^1 + a_5*T^2 + a_6*T^3 + a_7*T^4.

I think that fits format in CFX is :

Cp/R= a_1 + a_2*T^1 +a_3*T^2 + a_4*T^3 + a_5*T^4.

What do you think ?

The format

Cp/R= a_1 + a_2*T^1 +a_3*T^2 + a_4*T^3 + a_5*T^4.

is the original format used by Gordon/McBride, while

Cp/R= a_1*T^-2 + a_2*T^-1 + a_3 + a_4*T^1 + a_5*T^2 + a_6*T^3 + a_7*T^4.

is a newer format they have been using for a while now.

I do not know if CFX allows for a 7-coefficient fit of Cp/R.
