Radiation model in 2D

Hi all, I have a 2-D model that consists of a tube surrounded by air. This air is irradiated with a heat flux that is measured in W/m^2, and is transmitted through radiation to the tube. The air is modeled as a non-emitting media, so I have used the physics interface of Radiation in absorbing-scattering media, and radiation is studied using the Discrete Ordinates method. However, in this physics, I am required to introtuce the radiation intensity in W/(m^2·sr). Does anyone know hoy to convert this heat flux from W/m^2 to W/(m^2·sr), and which is the factor that I have to include? An answer would be very much appreciated. Thank you in advance.
