摘要

We study two discrete and one asymptotic approximations of the radiative-conductive heat transfer problem in a system of absolutely black round rods placed in a square box and separated by the vacuum. We obtain error estimates of order \(O\left(\sqrt{\varepsilon }\right)\) O ε , where ε is the rod diameter.
