  abstract: An analytical investigation was made of the radiant heat transfer between the surfaces of a gray enclosure filled with a non-reacting gas considering all multiple reflections between the surfaces. The problem was developed by writing two different heat transfer equations for each surface of the enclosure: Q[subscript i] = Σ[n above sigma, k=1 below sigma] A[subscript i]F[subscript i-k] (J[subscript i]-J[subscript k]) i = 1 ,2, 3, 4, ..., n (1) and Q[subscript i] = A[subscript i] (J[subscript i]-H[subscript i]) (2) where where Q[subscript i] is the net heat exchange between the ith surface and the rest of the enclosure; A[subscript i] is the area of the ith surface; F[subscript i-k] is the view factor between the ith and kth surfaces; J[subscript i] is the radiosity of the ith surface; H[subscript i] is the irradiation of the ith surface; and n is the total number of surfaces. The radiosity is composed of the emitted flux density, the reflected flux density, and the flu x density transmitted into the enclosure from the outside or J[subscript i] = σε[subscript i]T^4[subscript i] + ρ[subscript i]h[subscript i] + τ[subscript i]H'[subscript i] (3) where is the temperature; H'[subscript i] is the outside radiant flux density; ε is the emissivity; ρ is the reflectivity; and τ is the transmissivity of the surface. Eliminating H[subscript i] from Equations (2) and (3) gives: Q[subscript i] = A[subscript i] [(ε[subscript i] / ρ[subscript i] σT^4[subscript i]) + (τ[subscript i] / ρ[subscript i] H'[subscript i]) -- (1-ρ[subscript i] / ρ[subscript i]) J[subscript i]]. (4) For each surface of the enclosure there are three possible boundary conditions that can exist: (a) the temperature and the outside radiant flux density are known; (b) the net heat transfer is known; (c) neither of the above. Equations (1) and (4) are used, depending upon boundary conditions (a) or (b), to form a set of simultaneous linear equations with the radiosities as the unknowns. If boundary (c) exists, t…
