Influence of diffusely specular reflection on the transfer process in a gap

  • G. I. Vorob'eva


A quasidiffusion approximation is constructed for the problem of radiation transfer in a narrow gap in the case of diffusely specular reflection by the walls. The accuracy of the approximation obtained is investigated.
