Radiation

fullflow.Radiation

Diffuse-gray radiation exchange between two temperature nodes.

Radiation computes radiative heat transfer between two diffuse-gray surfaces using emissivities, radiating areas, and a view factor. Positive heat rate indicates net radiative heat transfer from temperature2 to temperature1.

This component can be used for surface-to-surface radiation or vacuum jacketed tube radiation.
