Hi EVERYBODY!

I want to simulate a solid particle tracking in a continuos nitrogen dominium in CFX 5.7.

I want nitrogen to absorb no radiative heat, therefore I set the radiation model to none; but I want the solid particles to absorb radiative heat.

How can I do?

Please answer me!!!Thank you!!!

Hi,

You will need a radiation model to do this so turn it back on. Set the absorption coefficient of N2 to 0 so it does not absorb any radiation.

Thank you for your answer Glenn!

I set the nitrogen absorbtion coefficient to zero but the simulation result was the same of the simulation without any radiation model switched on: the particle temperature was the same in both simulations.

Do you have any other suggestions?

Thanks a lot!!!!
