Radiation problem
 

Hello world,

I am trying to simulate a heat trasfer problem. In my problem i have put a solid body at the bottom of a room with a heat release rate source. and room is full of air cell zone. Now wanna apply a radition model. and want to see the temperature profile and heat dissipation in the air and bottom and side walls. all the boundary of my model is wall.

so which radiation model should i use and i am confused about the wall wall and wall-air interaction because of radiation model ???

if i apply a radiation model in the solid body which is wall in b.c how does ir work with another wall that is in direct contact of the solid all and what about the interaction of the solid body and air interaction bcz of radiation???

pls help me. i am new in using fluent

thank you very much
