Theory for the Moist Air Version of the Heat and Moisture Transport Interface
The Moist Air version of the
Heat and Moisture
multiphysics coupling implements the following equations in domains for heat and moisture transport:
(4-154)
(4-155)
(4-156)
(4-157)
(4-158)
(4-159)
See
Theory for Heat Transfer in Moist Air
and
Theory for Moisture Transport in Air
for more details about the notations.
In addition, on boundaries where evaporation or condensation takes place, the following equation is solved:
(4-160)
The heat transfer and moisture transport equations are coupled through:
•
the definition of the effective thermal properties accounting for vapor concentration in moist air,
•
the definition of the diffusive flux of enthalpy (
Equation 4-156
),
•
the definition of the latent heat source from the evaporation source on surfaces (
Equation 4-160
),
•
the definition of the vapor saturation in function of the temperature (
Equation 4-159
).
