Abstract : A method is described for applying the numerical solution of integral equations of radiation to special problems in radiative heat transfer among four bodies placed in a diathermal medium. The problem consists of solving a finite set of linear inhomogeneous algebraic equations. The solutions are discussed in detail for two types of boundary conditions: (1) the fundamental case (temperature given at all nboundaries); (2) the mixed case (temperature given for boundary n1 only, the rest being radiant flux conditions). Both cases are applied to a special problem consisting of four zones in a closed system, three of which are gray bodies and one black. The three parameters evaluated in each case are: surface radiation density, spherical radiation vector, and the spatial density of the radiation. (Author)
