Drainage plane
Drainage plane
In modeling any drainage plane, is there any way to model the actual drainage? Can a moisture sink be inserted at another layer to represent liquid water drained away, or is an air source and evaporation the only way?
Re: Drainage plane
If the water is brought in by a moisture source, you can use the "source term clipping" feature to limit the water content in the source region to a specified maximum value. This corresponds to the assumption that the material containing the moisture source can only hold a maximum amount of water, any excess automatically being drained by running off.
However, if the moisture does not come from a moisture source but accumulates for other reasons (e.g. condensation of water vapor migrating through the component), then there is no type of moisture sink which would wait for the moisture to exceed some threshold value and then drain the surplus water away.
Hm, maybe we should introduce such a feature simulating the run-off of condensing moisture... But currently it does not exist.

Hello,
is there an update for this problem? I've a wall with a unventilated cavity and steal plate on the outside (ship's hold). However, the condensation can be drained by pumping.

Re: Drainage plane
Hello Francis,
was nice to have met you at ASHRAE this June, how are things in Colorado?
Sorry I must have overseen your recent post. There is no "update" for this problem, however there is always and option to program specific plug-ins for the calculation kernel to realize a draining.
I could do such services for you. Let me know, If I should send you a proposal.
