Not possible to apply emissivity and thermal radiation on same surface

Sivateja Kasireddy Jul 28, 2014 11:33 AM

I have a problem in solid works flow simulation that, it is not possible for me to give the conditions like emissivity and thermal radiation on same surface, may i know the reason what make that not accepting the both conditions on same surface.

NOTE: The surface which i considered is transperent glass.

what is the physical application you are trying to replicate?

  i am working on the super market refrigerator doors, i want to check the effect of emissivity on the glass door along with the effect of thermal radiation on that door

    where does the radiation come from?
    
    i guess i don't understand why you need to apply both conditions on the same face

      The radiation is comming from the ambient atmosphere
      one side it is 30F and on other side it is 75F both are seperated by a glass chamber

        if it is coming from ambient, there is no need to apply radiation to the wall, it will come from "the environment" and you should only need to apply the emissivity override
