Black Body Radiation Calculation
Calculates the maximum thermal radiative power (black-body emissive power) that any opaque surface can emit at a given temperature using the Stefan–Boltzmann law.

Black-body radiation flux sets the benchmark for radiant heat transfer in furnaces, reactors, and safety studies. Real surfaces emit less, so this value is the reference from which emissivity and view-factor corrections are applied.
