Thermal radiation net power
estimates the net radiative heat transfer between a gray body and a large isothermal environment.
symbols, variables and units
ε: emissivity; σ: W/(m²·K⁴); A: m²; T, T_s: K.
applicable conditions and boundaries
Gray body, viewing angle factor is approximately 1; complex geometry requires radiation network.
