Abstract: Combined with spectral band model, control volume method and discrete transfer (DT) method are employed to investigate numerical calculation dealing with the transient combined radiation-conduction heat transfer in three dimensional cylindrical semi-transparent medium. The first and the third nonlinear boundary conditions are both considered. Compared with Zone method and improved Monte-Carlo approach, the calculated results by this method are reliable and more precise.

Key words: semi-transparent medium, combined radiation-conduction heat transfer, discrete transfer method, numerical method
