Detailed Description

greyMeanAbsorptionEmission radiation absorption and emission coefficients for continuous phase

The coefficients for the species in the Look up table have to be specified for use in moles x P [atm], i.e. (k[i] = species[i]*p*9.869231e-6).

The coefficients for CO and soot or any other added are multiplied by the respective mass fraction being solved

All the species in the dictionary need either to be in the look-up table or being solved. Conversely, all the species solved do not need to be included in the calculation of the absorption coefficient

The names of the species in the absorption dictionary must match exactly the name in the look-up table or the name of the field being solved

The look-up table ("speciesTable") file should be in constant

i.e. dictionary

LookUpTableFileName "speciesTable";

EhrrCoeff0.0;

CO2 { Tcommon 300.; // Common Temp invTemp true; // Is the polynomial using inverse temperature? Tlow300.; // Low Temp Thigh 2500.; // High Temp

loTcoeffs // coeffs 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 // coeffs for T > Tcommon ( 18.741 -121.31e3 273.5e6 -194.05e9 56.31e12 -5.8169e15 );
