three-dimensional hygric redistribution

Post by Peterbilt »

I just want to confirm that none of the WUFI programs take into account 3-dimensional hygric redistribution of water or vapor content. In other words, WUFI can't evaluate how water condensing on the interior of structural sheathing on an exterior wall would be distributed into an adjacent framing cavity filled with cellulose insulation?

Dear Peter,

WUFI can calculate 3D hgric transport for radial symmetric geometries only for other geometries only the 2D transport (e.g. with WUFI 2D) can be assessed. In addition for sorptive materials (e.g. cellulose fiber) the concept of dew water loses its explicitness. Liquid water (dew water in its original definition) only occures if the pores of the sorptive material are already saturated.

kind regards,
