Radiative solar heating of surfaces with buoyantSimpleFoam

Dear Faomers,
I am trying to simulate solar heating and the resulting convection. I would like to treat the heated solid boundaries as 1D rather than modeling the internal temperature profiles with multi region. I belive this is possible in theory, but I can't seem to find an example of an openFoam casefile that does this. From my interenet searches, it seems that this boundary condition might be the right one for what I described above: Code:
{ type externalWallHeatFluxTemperature; mode coefficient; Ta constant 300.0; h constant 10.0; thicknessLayers (0.1 0.2 0.3 0.4); kappaLayers (1 2 3 4); kappaMethod fluidThermo; qr qr; value $internalField; } But it crashes after the temperature goes below absolute zero. Can anyone point me in the right direction? Thanks |

I am really struggling with this and am very surprised I can't find an example casefile where there is solar radiation, and a surface actually changes temperature without using a chtMulitRegion solver. For example, if I wanted to make the surface temperature change in the simpleCarSolarPanel tutorial, can anyone tell me what boundary condition to use? Or alternatively, does anyone know of a textbook or journal papers that give a good introduction to this type of modeling in openFoam?
