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 ( 18.741 -121.31e3 273.5e6 -194.05e9 56.31e12 -5.8169e15 ); |
