In this video, we will see how to apply Internal Radiation in Ansys Discovery. This will be significant when working with high-temperature conjugate heat transfer (CHT) cases, as radiant heat flux can become a dominant factor compared to convection or conduction.

You’ll learn two main methods for defining internal radiation: through the fluid-solid interface or using wall conditions and we’ll see how to define internal emissivity values.
