InletStagnationPressureTemperature1Phase
This is a single-phase 1-D flow boundary component in which the stagnation pressure and temperature are specified. This boundary is typically used when fluid is expected to flow from an infinitely large tank where the pressure and temperature are known.
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 stagnation pressure,
, the provided exterior stagnation temperature, and
, the interior velocity.
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 exterior pressure, assumed to be equal to the provided exterior stagnation pressure ,
, the interior density, and
, the interior velocity.
