The objective of this paper is to present a methodology to solve the inverse problem of radiative exchange within enclosures composed of diffuse-gray surfaces. The mathematical model is presented in terms of a set of linear integral equations for the outgoing radiative energy rates (radiosities). Due to the ill-conditioned nature of the set of linear equations obtained from the discretization of the mathematical model, a regularized solution based on the Modified Truncated Singular Value Decomposition (MTSVD) is computed. Numerical results indicate that an inverse solution of the radiative exchange within gray enclosure can be computed within some degree of accuracy. Results also indicate that solutions can be obtained for a limited range of boundary conditions.
