Theory for the Moist Porous Media Version of the Heat and Moisture Transport Interface
The Moist Porous Media version of the
Heat and Moisture
multiphysics coupling implements the following equations in domains for heat and moisture transport:
(4-169)
(4-170)
(4-171)
(4-172)
(4-173)
(4-174)
(4-175)
See
Theory for Heat Transfer in Moist Porous Media
and
Theory for Moisture Transport in Porous Media
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 in liquid and gas phases
•
The liquid water saturation and velocity field used to define the convective heat flux
•
The diffusive flux of enthalpy in moist air and the liquid capillary flux (
Equation 4-171
)
•
The definition of the latent heat source from the evaporation source in domains (
Equation 4-172
)
•
The definition of the vapor saturation in function of the temperature
