The Heat Transfer in Moist Air Interface
The Heat Transfer in Moist Air interface () is automatically added when the Moist Air version of the predefined multiphysics interface Heat and Moisture Transport is added. A Moist Air (HT Interface) model is active by default on all domains.
It is used to model heat transfer in moist air by convection and diffusion, by using thermodynamics properties defined as a function of the quantity of vapor in the moist air.
When this physics interface is added, the following default nodes are added in the Model Builder: Moist Air, Thermal Insulation, and Initial Values. Then, from the Physics toolbar, add other nodes that implement, for example, boundary conditions. You can also right-click Heat Transfer in Moist Air to select physics features from the context menu.
The settings are the same as for The Heat Transfer in Fluids Interface. This means that a first order discretization is used by default for the temperature.
See Physical Model, Consistent Stabilization, Inconsistent Stabilization, Discretization, and Dependent Variables for details.
The feature nodes are the same as for The Heat Transfer in Fluids Interface, with in addition the Moist Air node.
