Theory for the Building Materials Version of the Heat and Moisture Transport Interface
The Building Materials version of the
Heat and Moisture
multiphysics coupling implements the following equations for heat and moisture transport, derived from
Ref. 15
:
(4-152)
(4-153)
See
Theory for Heat Transfer in Building Materials
and
Theory for Moisture Transport in Building Materials
for more details about the notations.
The heat transfer and moisture transport equations are coupled through:
•
the definition of the effective thermal properties accounting for moisture content,
•
the definition of the latent heat source from the evaporation source in domains,
•
the definition of the vapor saturation in function of the temperature.
