JIMENEZ-AQUINO, J.I.  y  VARELA, J.R.. Two stream approximation to radiative transfer equation: An alternative method of solution. Rev. mex. fis. [online]. 2005, vol.51, n.1, pp.82-86. ISSN 0035-001X.

An alternative analytical method of solution to radiative transfer equation in the two-stream approximation is studied. The method is formulated in terms of the diffusion-type equation for radiative transfer associated with the fluxes (irradiances) F_d = F⁺ - F^- and F_s = F⁺ + F^-, where F⁺ and F^- are defined as the upward and downward fluxes respectively. The diffusion-type equations are independent and therefore the method of solution is algebraically easier and faster than that used to solve the two coupled differential equations associated with F⁺ and F^-.

Palabras llave : F⁺ upward flux; F^- downward flux.
