radiation in flow simulation

I want to consider radiation in my flow simulation model. The model is a hollow cylinder with a bar in the middle as heat source and air as a fluid. The analysis type is an internal one. I want to consider radiation from the heat source surface and see how it affects the temperature inside the cylinder and also across the cylinder wall. Just wonder how to define my radiative surfaces? Thanks.
