Inflow
The Inflow node adds a boundary condition for an inflow boundary, defining the composition of the mixture. The node is available for exterior boundaries. The mixture composition can be specified using the following quantities:
•
Mass fractions: ωi = ω0,i
•
•
•
•
The density: ρi = ρ0,i
•
The node requires input for all species. (The Mass Fraction node can be used to specify boundary mass fractions for a subset of the active species in the interface.)
Inflow
Select a Mixture specification:
•
Mass fractions (the default) to enter mass fractions (ω0,ω1, for example)
•
Mole fractions to enter mole fractions (x0,ω1 for example)
•
Molar concentrations (SI unit: mol/m3) to enter molar concentrations (c0,ω1, for example)
•
Number densities (SI unit: 1/m3) to enter number densities (n0,ω1, for example)
•
Densities (SI unit: kg/m3) to enter densities (ρ0,ω1, for example)
•
Mass flow rates (SI unit: kg/s) to enter the total mass flow over the boundary (Jin,ω1, for example)
Enter a value or expression in the field for each species except for the one computed from the mass constraint.
