Hello friends,

I am running a case with only radiation effect in a cavity, where left side wall temperature is fixed at 348K, right side is 298. top and bottom are maintained adiabatic. I am getting radiative heat flux along hot wall is 0.04. this result is not matching with the literature value(which is ~548).
Does anyone have experience in this kind of problems. please share your suggestions. what may the be the value? how to get the improved value? please reply.

Thanks
srikanth.
