PWCNSFVMomentumFluxBC
Flux boundary conditions for porous momentum advection.
This object is the porous medium version of WCNSFVMomentumFluxBC.
The momentum flux is:
with the momentum flux, the density, the fluid superficial velocity (assumed normal to the surface here), the porosity of the medium, the mass flow rate, and the inlet area.
There are two options for specifying the momentum flux:
specifying a mass flow rate postprocessor, which is then divided by the area of the inlet, which may also be a postprocessor.
specifying an inlet superficial velocity postprocessor and a density functor. The functor is usually a functor material property, defined by a GeneralFunctorFluidProps.
The scaling factor may be used if the inlet is not aligned with the X or Y direction, in which case a projection is necessary and this boundary condition should be used for both components of the momentum equation.
This boundary condition works with postprocessors, which may be replaced by constant values in the input. The intended use case for this boundary condition is to be receiving its value from a coupled application, using a Receiver postprocessor.
Input Parameters
- area_ppInlet area as a postprocessor
C++ Type:PostprocessorName
Controllable:No
Description:Inlet area as a postprocessor
- direction0 0 0The direction of the flow at the boundary. This is mainly used for cases when an inlet angle needs to be defined with respect to the normal and when a boundary is defined on an internal face where the normal can point in both directions. Use positive mass flux and velocity magnitude if the flux aligns with this direction vector.
Default:0 0 0
