Radiative equilibrium problem for an absorbing emitting medium between plane parallel diffuse surfaces can be expressed by the Fredholm equation of the second kind. In this paper a variational formulation of the problem is obtained in terms of a functional. Dimensionless temperatures and heat fluxes for various optical thicknesses are then solved by the Ritz method. Results are expressed in terms of a third order polynomial with two coefficients and are very close to the exact solution of Heaslet and Warming. Copyright (C) 1997 Elsevier Science Ltd.
