The Heat and Moisture Transport Interfaces
The Heat and Moisture Transport interfaces couple heat transfer and moisture transport in building materials and moist air.
The Building Materials version of the Heat and Moisture Transport multiphysics interface combines the Heat Transfer in Building Materials and Moisture Transport in Building Materials interfaces. A Heat and Moisture multiphysics node is automatically added to couple these interfaces. It takes in account heat and moisture storage, latent heat effects, and liquid and convective transport of moisture. In addition, the temperature dependency of the moisture properties is automatically accounted for.
When the Moist Air version of the predefined Heat and Moisture Transport interface is added, it combines the Heat Transfer in Moist Air and Moisture Transport in Air interfaces to model coupled heat and moisture transport in moist air, by modeling moisture transport by vapor diffusion and convection and heat transfer by conduction and convection with moisture-dependent thermodynamics properties.
The versions of the Heat and Moisture Transport multiphysics interface are described in the Heat Transfer Module’s User’s Guide:
