Abstract: On the basis of characteristics of radiation transfer in the cavity, the author discussed the necessity and feasibility of calculating strategy which is to solve transport equation in the cavity and solve diffusion equation in the cavity wall. A method which links interface calculation of the two regions is presented.some numerical test results are also also given with corresponding conclusions.

Key words: radiation transfer, domain decomposition, coupling transport-diffusion method
