radiation model
hello, i am a new user of CFX and i want to simulate a combustion in a oven. So, i would use the multigray model in order to take the contribution of CO2 and H2O on the radiation emissivity. But i don't understand how to fill in "weight" and "absorption coefficient", where will i find this information?
The CFX Solver Theory of CFX gives a chart with some coefficients but i don't know how use it. Do i make a expression with the linear finction of Tg ??? Thanks a lot to help me. P.S: excuse the poor english of a french boy. |
Re: radiation model
Dear Alexis,
Start CFX-Pre, select File->New Simulation, fill the name and select Library Template. You then will see a template for multigray radiation. This template is for Methane-Air combustion using the 4-gray gas coefficients described in the documentation. Good luck, Opaque.. |
