Radiative transfer equation
A modification of the Eddington approximation to the equation of radiative transfer is suggested. The basic element of this approach is the derivation of an approximate angular distribution for ...However, the rate of energy transfer is less than the equation for the radiative heat transfer would predict because the Sun does not fill the sky. The average emissivity (e) of the Earth is about 0.65, but the calculation of this value is complicated by the fact that the highly reflective cloud coverage varies greatly from day to day. There is ...The integral form of the equation of radiative transfer is developed for an absorbing, emitting, gray, isotropically scattering, inhomogeneous, solid cylinder with internal energy sources, subjected to externally incident radiation, and having both specular and diffuse reflection at the boundary surface. Under this transformation, the number of ...
