Diffusion Approximation

Diffusion Approximation is a mathematical modeling technique in radiation transport theory that belongs to the class of approximate methods for solving the radiative transfer equation, distinguished by its assumption of nearly isotropic radiation intensity and its use of Fick's law to relate the radiation flux to the gradient of the scalar intensity.
