I am using the finite Volume Method and I am looking for books and articles dealing with the modelling of radiation in Heat transfer. ( View Method and so on). I am glad for every contribusion

Please visit the following webpage. We published a few papers on radiation heat transfer calculation using the finite volume method.

Please feel free to contact me with questions.

HI, DIFFUSION APPROXIMATION IS VALID FOR OPTICALLY THICK MEDIA LIKE GLASS MELTS. YES IT REDUCES MATEMATICAL COMPLEXITY BUT RADIATION ITSELF IS NOT A DIFFUSION PROCESS. FOR COMBUSTION SPACE WHICH SHOULD BE TREATED AS OPTICALLY THIN MEDIA, RADIATIVE TRANSPORT EQUATION (RTE) SHOULD BE SOLVED USING AN APPROXIMATE RADIATION MODEL LIKE DISCRETE TRANSFER, DISCRETE ORDINATES OR FINITE VOLUME METHOD.

Hi there. Yes, I mentioned that the approximation I suggested is for optically thick media, where the radiation is in equilibrium with the gas. There is even a similar treatment for optically thin, but I guess that it does not apply here for the specific application. Cok merci. Dr. P. Godon, STScI.

P1 method,which is a kind of diffusion equation, is used for solving the opticallly thin media, and for the optically thick media, we must use another algorithm, like as S4 method. S4 method is accurate compared to p1 method but the cpu time is very long,

so the new alogorithm adopting the advantages of those two method(p1 method and s4 method) is needed, that is accurate prediction with reduced cpu time.

for more details , see the book "RADIATIVE TRANSFER EQUATION" BY OZISIK
