3.4.4 Including Fiber Radiation Interaction

In some situations radiative heat exchange is important. If you are using ANSYS FLUENT's P-1 radiation model or ANSYS FLUENT's discrete ordinates (DO) radiation model, you can consider the effects of irradiation on the cooling and heating of the fibers. When you are using the DO radiation model, the effects of the fibers upon the DO model is considered as well. If the DO radiation model is enabled, the Fiber Radiation Interaction option will be turned on and you will need to enter the fiber's Emissivity under Properties in the Fiber Model dialog box (Figure  3.4.1).
