buoyantSimpleRadiationFoam
 
hello dear foamer

i would like to model a greenhouse with OpenFOAM (buoyantSimpleRadiationFoam).
consider a box with fixed side walls, celing and floor

could u please answer following questions:


1)whats G in 0 folder? and whats the meaning of
{
type MarshakRadiation;
T T;
emissivity 1;
value uniform 0;
}

2) celing is glass ,and sun shines come cross the glass, how can i define boundary condition (G) for celing?

3)in constant/radiationProperties:
whats is E ?

4) i tried to run the tutorial in laminar! but the solver crash! after several iterations, rho diverges and difference between rho max and min gets too high, what should i do? ( may be a good question is that when a flow in a closed box like green house is turbulent? )

thank you

Dear Nima,

just to know, have you solved this? I think I am going to try this, too. So, if I have problems, I'll ask you.

Thanks,

Samuele
