Hi
I wonder how can I set the sky emissivity in solar radiation simulation with star ccm+. Thanks in advance |

The help file of star ccm+ does not contain sky emissivity ,In solar collector tutorial they set the emissivity for many parts but they did not show which one is for the sky , by the way sky emissivity has the value of around 0.74 .
