DO radiation model

nima_nz · October 19, 2015, 11:25

Hi,
I have an enclosure with one semi-transparent wall and all other walls are opaque. After the code converged, the heat flux results show that all the negative heat flux on the semi-transparent wall, when I have the solar load, and convective boundary condition with 30 C outdoor condition and all other walls are set to zero heat flux. So, when the temperature of the room should be higher that outdoor temperature, it's less.
I appreciate that if you help me.

Hi nima_nz. Is it a steady state simulation? Do you have any past research papers which investigate a similar configuration?

Yes, it is a steady simulation. I didn't find a paper which is exactly like my model, but there is some research which can be helpful, like:
