Radiosity (heat transfer)
Radiosity is the total of emitted and reflected radiation leaving a surface, in the fields of optics and heat transfer. Hemispherical radiosity Jλ(λ) is the integral of the spectral intensity of reflected plus emitted radiation over the hemispherical solid angle. The total hemispherical radiosity J is the integral of the hemispherical radiosity over all wavelengths:
Additional recommended knowledge
The radiosity method is used to solve for the radiative heat transfer between a number of surfaces. Because the radiation hitting each surface is determined by the temperatures of of all the other surfaces, this method requires the solution of a system of simultaneous equations using matrix methods. For more information see Radiosity (computer graphics).
