InletDensityVelocity1Phase
This is a single-phase 1-D flow boundary component in which the density and velocity are specified.
Usage
This component must be connected to a FlowChannel1Phase. See how to connect a flow boundary component.
The user specifies the following parameters:
The formulation of this boundary condition assumes flow entering the flow channel at this boundary.
Reversible flow: If exit conditions are encountered, then the boundary condition is automatically changed to an outlet formulation. This behavior can be disabled by setting the "reversible" parameter to false
.
Input Parameters
- reversibleTrueTrue for reversible, false for pure inlet
Default:True
C++ Type:bool
Unit:(no unit assumed)
Controllable:No
Description:True for reversible, false for pure inlet
Optional Parameters
- control_tagsAdds user-defined labels for accessing object parameters via control logic.
C++ Type:std::vector<std::string>
Unit:(no unit assumed)
Controllable:No
Description:Adds user-defined labels for accessing object parameters via control logic.
- enableTrueSet the enabled status of the MooseObject.
Default:True
C++ Type:bool
Unit:(no unit assumed)
Controllable:No
Description:Set the enabled status of the MooseObject.
Advanced Parameters
Formulation
This boundary condition uses a ghost cell formulation, where the ghost cell solution is computed from the following quantities:
, the provided exterior density,
, the provided exterior velocity, and
, the interior pressure.
If the boundary is specified to be reversible ("reversible" set to true
) and the flow is exiting, the ghost cell is instead computed with the following quantities:
, the provided exterior velocity,
, the interior density, and
, the interior specific total energy.
