Hello,


for my 2D problem setup I would like to model the wall between the external, hypersonic fluid (Ma 8, ..., 12), and the solid airfoil/geometry (which is meshed as a solid) as a radiation adiabatic wall.

To my understanding in theory this means that the heat conduction (gas->wall) equals the heat radiation (wall->gas). Please correct me if I'm wrong.



I know how to model the standard adiabatic wall aswell as the isothermal and coupled wall conditions as fluent makes setting these up quiet easy.



Which settings do I need to set to obtain a radiation adiabatic wall boundary condition?



I searched this forum and several papers for an answer but I couldn't find anything regarding the fluent setup.



Thank you very much for your help.


Best regards

My current idea is to write a UDF which describes the ratiation heat flux from the solid towards the fluid. If anyone has experience on this or suggestions why this should work or not I would be happy.




best regards
