Inflow

The 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 mole fraction: xi = x0,i

•

The molar concentration: ci = c0,i

•

The number density, which describes the number of particles per volume: ni = n0,i

•

The density: ρi = ρ0,i

•

The mass flow rates.

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 :

•

(the default) to enter mass fractions (ω0,ω1, for example)

•

to enter mole fractions (x0,ω1 for example)

•

(SI unit: mol/m3) to enter molar concentrations (c0,ω1, for example)

•

(SI unit: 1/m3) to enter number densities (n0,ω1, for example)

•

(SI unit: kg/m3) to enter densities (ρ0,ω1, for example)

•

(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.
