Hi All,I am trying to solve a problem for summer conditions. I have already included the heat flux boundary condition for windows (by conductive and convective heat transfer).How can I take into account the heat source due to soaler heating of window. (I have the data for heat generation rate watt/m3).Regards, Vishal

Hi all, have any of you simulated an HVAC multiregion case (i.e. room with windows sorrounded by external air)?, and if yes you might have encountered (at least I had) that the explicit coupling for the energy equation tends to be quite slow to converge (of course, it depends on the case) .How did/would you handle/overcome this problem? (implicit coupling,block matrix)

Hi, we at Engys have developed an extensive HVAC tool box for OpenFoam, that includes a much faster DOM radiation solver, solar radiation, evaporation/condensing of humidity, CO2 production from humans, and many more features realted to human comfort simulations in vehicels and buildings. As a solver we use buoyantBoussinesqSimpleFoam (or buoyantBoussinesqPisoFoam). Here an example for a generic aircraft cabin: http://www.youtube.com/user/engysCFD#p/u/9/QaXziL85cOEThomas

Hi all, I have been using OpenFoam for just over two years now but have not much experience in HVAC simulation. What OpenFOAM® solver would you use for an aircraft cabin problem to calculate relative humidity and temperature maps inside the cabin? Cheers
