I have implemented the WSGGM radiation sub-model based on Fluent User Guide and the following references:

• T. F. Smith, Z. F. Shen, and J. N. Friedman. "Evaluation of Coefficients for the Weighted Sum of Gray Gases Model". J. Heat Transfer. 104. 602608. 1982.
  
• R. Siegel and J. R. Howell. "Thermal Radiation Heat Transfer. Hemisphere Publishing Corporation, Washington DC. 1992.

https://github.com/arvindjp/OpenFOAM...rptionEmission

To compile:

cp -rf wsggmAbsorptionEmission $FOAM_SRC/src/thermophysicalModels/radiation/submodels/absorptionEmissionModel/.
 wmake

To select WSGGM model, use the following options in radiationProperties:

  absorptionEmissionModel wsggmAbsorptionEmission;

  wsggmAbsorptionEmissionCoeffs
  {

      meanBeamPathAutoCalcMode      true;
      sector sector    [ 0  0  0  0  0  0  0] 360.0; //Degrees
      pathLength pathLength [ 0 1  0  0  0  0  0]  0.1; //m
      emissivityCoeffs 3(  0.4201 6.516 131.9 );
      fittingFactors  
          3        
          (
           4(6.508e-1 -5.551e-4 3.029e-7  -5.353e-11)
           4(-0.2504e-1  6.112e-4  -3.882e-7  6.528e-11)
           4(2.718e-1 -3.118e-4  1.221e-7  -1.612e-11)
          );

  }

Please let me know your feedback.
Thanks,

Thank you very much for extended radiation sub model.
When I compile this model and run the code with radiation properties, maximum temperature increasing while temperature reach to without applying temperature condition. can you help me for apply WSGGM model?

Hi

I tried to compile this, but I am getting this error message:
"cp: cannot stat ‘wsggmAbsorptionEmission’: No such file or directory"

I want to add WSGGM model to my radiation study, but I don't know how.

Instead of using the cp -rf command that the author mentioned, you can simply copy the wssgmAbsoprtionEmisison folder in sub model directory present in src/thermophysicalModels/radiations. Then execute "wmake" command inside wsggmAbsorptionEmission directory.
