Room with moisture

Fabio_77 · April 1, 2011, 07:13

Hi guys, do you have an idea how to modelize moisture in a room?

Thank you

Any idea????

You transport humidity as a passive scalar. Its all about having the right boundary conditions, initial conditions and diffusivity. If you want to do condensation/evaporation it becomes quite a bit more complicated.

Hallo eugene,

do have some more informations and maybe some papers about the transport equation and the backlash of the energy for example.

Following the same ideia, what solver should i start with to model evaporation? I want an interface air/water and the evaporation effect (ex: a pool in a closed room). bubbleFoam? buoyantBaffleSimpleFoam?

Thanks in advance

in the reactingParcelFilmFoam is evaporation inclusive

Thank you Preibe! That was exactly what i was looking for.
