When we apply the Solar Load Model in Ansys Fluent, the value of External Radiation Temperature has to be put in the Thermal (radiation and mix) Tab. Now, I am confused here; if I apply this temperature as input to my wall, will it consider the boundary condition as the constant temperature boundary condition? In that case, there is no point in finding the temperature (as output) for that wall. Therefore, I am curious to know about External Radiation Temperature.
Dear Jishnu Handique,
It is the temperature that an external radiation source imposes on the outside of the system. This temperature will used to calculate the heat flux to the wall.
I will also recommend the you must read https://www.afs.enea.it/project/neptunius/docs/fluent/html/ug/node478.htm
