problems in DO model with semi-transparent media

Jiuan · October 13, 2009, 17:28

Hi All,

I am modeling a radiation heat tranfer using DO model involving semi-transparent media (i.e. glass). I got abnormal temperature distribution in some regions of geometry, which means the temperature in those regions are higher than that they should be. I change the semi-transparent media to opaque. Problem is solved. But this is not the real case. Please help. Thanks so much.

Hi,

Did you manage to solve this problem? I have a similar issue. When the refractive index is changed from 1 to 1.5 (i.e. glass), results are completely different.
Thank you in advance.
Best regards, Petar

Hi everyone,

I have same problem, does anyone have solution for this problem (how to model semitransparent media in fluent (DO model))
