This subnode defines the velocity field ul and the saturation
sl of the liquid water phase used in
Equation 6-6 of the
Moist Porous Medium parent node. The density
ρl (SI unit: kg/m
3), the heat capacity at constant pressure
Cp,l (SI unit: J/(kg·K)), and the thermal conductivity
kl (SI unit: W/(m·K)) are defined as functions of temperature.
The Liquid water saturation,
sl, used to evaluate the effective thermodynamics properties in the
Moist Porous Medium parent node, should be set.
The default Velocity field, liquid water,
ul, is
User defined. For
User defined, enter values or expressions for the components based on space dimensions. Or select an existing velocity field in the component (for example,
Velocity field (spf) from a
Laminar Flow interface).
If the node was added automatically after selecting the predefined multiphysics interface Heat and Moisture Transport, the liquid saturation and liquid velocity of the multiphysics node
Heat and Moisture are used by default, and the section is not editable. To edit the
Liquid water saturation and
Velocity field, liquid water fields, click
