Radiation

September 27, 2002, 22:10

Hi Rami,

I have found your published paper and I will certainly go through it. But just from the abstract of your paper, it seems that the paper apply DOTS on radiative transport equation (RTE) . So my question is in a situation of fluid medium which is not participating or in other word, the medium is transparent to the thermal radiation, then radiative heat flux term should not be appeared in the energy equation of the fluid (but the heat energy will get in the fluid through the conduction at the solid-fluid interfaces), how can you apply DOTS/DOM method to solve RTE (when RTE is not existed at all)?

Well, I understand that DOM is a purely mathematical method for solveing integral-differential equation, and it is not limited in solving RTE. I believe it should have no problem to use it to solve the transport equations of the fluid. But specifically to the radiation exchange between solid boundaries with only non-participating medium involved, would you please explain a little bit more detail on how you apply the DOM/DOTS in solving RTE?

Regards,

Adam

Hi Adam,

I suspect this discussion becomes too specific and would not be of interest to most of this forum audience. I therefore suggest we continue through e-mail.

However, just a short answer to your question: we use the DOM merely to solve the radiative transfer equation for given temperature. The resulting net radiative source is applied as a source term to the fluid and at boundaries. The fluid equations are solved (including coupling terms, e.g., volumetric convetive HT) and new fluid and solid temperatures are estimated. This iterative process is continued until converged.

PS., we did not publish this method yet, and it is certainly beyond the scope of the paper I mentioned. If you are interested, I will e-mail you more details.

hi friends
i want to calculate radiation heat transfer by zone method.
i have all formula but i dont know any thing about udf.
please help me.

Radiations are an important topic in the current world of nuclear devices. This document might help you in studying this process.
