radiation in fluent

    • ibtissam


      can some one , tell to me how can i activate  radiation in my model (Discrete ordinate) 

      my geometry consists of two solid layers in contact submetted to radiation. and how can i activate the DO/ enrgy coupling?

      i want know what mean the external radiation temperature (exterioir radiation) and the free stream temperature (convection)

      I chose the first layer as semitransparent, so a direct irradiation and diffut are displayed, why?

      thank you

      I watched all three videos. May I know how to apply radiation heater (near infrared radiation heater), not the solar radiation?

      The second video clip seems helpful to my question

      You can set wall temperatures, if you want a radiant component that heats up a zone then you need to add an energy input (wall boundary or volume source) to suit.
