Outlet1Phase

This is a single-phase 1-D flow boundary component in which the pressure is specified. This boundary is typically used when the boundary is anticipated to be an outlet.

Usage

This component must be connected to a FlowChannel1Phase. See how to connect a flow boundary component.

The user specifies the following parameters:

  • "p": the pressure.

The formulation of this boundary condition assumes flow exiting the flow channel at this boundary.

Input Parameters

  • inputName of the input

    C++ Type:BoundaryName

    Unit:(no unit assumed)

    Controllable:No

    Description:Name of the input

  • pPrescribed pressure [Pa]

    C++ Type:double

    Unit:(no unit assumed)

    Controllable:Yes

    Description:Prescribed pressure [Pa]

Required 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 Ughost\mathbf{U}_\text{ghost} is computed from the following quantities:

  • pextp_{\text{ext}}, the provided exterior pressure,

  • ρi\rho_i, the interior density, and

  • uiu_i, the interior velocity.
