Hi,
I am using firefoam solver, planning to simulate 3DPoolfire. while changing the radiation property I encountered difficulty in finding the coefficients (a0 a1 a2 a3 a4 a5). I used Cp and T values from SR Turns book between T=200-2500K, but the obtained coefficients are not matching with the tutorial values,

Someone please guide me what I maybe missing here.

CO2
{
Tcommon 200; //Common Temp
invTemp true; //Is the polynomio using inverse temperature.
Tlow 200; //Low Temp
Thigh 2500; //High Temp

loTcoeffs //coefss for T < Tcommon
(
0 // a0 +
0 // a1*T +
0 // a2*T^(+/-)2 +
0 // a3*T^(+/-)3 +
0 // a4*T^(+/-)4 +
0 // a5*T^(+/-)5 +
);
hiTcoeffs //coefss for T > Tcommon
