This subnode defines the velocity field ug and the moisture-dependent thermodynamics properties used for the moist air phase in Equation 6-6 of the Moist Porous Medium parent node. The density ρg (SI unit: kg/m3), the heat capacity at constant pressure Cp,g (SI unit: J/(kg·K)), and the thermal conductivity kg (SI unit: W/(m·K)) are defined as functions of the amount of vapor in the moist air phase.

See Heat Convection and Thermodynamics, Moist Air for details on settings.
