Plenum Temperature

Gives an estimate of the temperature of the gas in the plenum

note:Often Created by an Action

This object can be set up automatically by using the PlenumTemperature action.

Description

PlenumTemperature gives an estimate of the temperature of the gas in the plenum. This is done by computing a volume weighted average temperature using gap sizes between surfaces.

A typical use is to pair a set of fuel surfaces (inner_surfaces) with a corresponding set of cladding surfaces (outer_surfaces). Another possible use is to pair the inner radius of the cladding (inner_surfaces) with the outer radius of the fuel (outer_surfaces). It is also possible to pair up surfaces automatically for a discrete pellet mesh using the num_pellets option.

Input Parameters

    Description:The name of the variable that this boundary condition applies to

  • boundaryThe list of boundary IDs from the mesh where this boundary condition applies

    C++ Type:std::vector

    Description:The list of boundary IDs from the mesh where this boundary condition applies

Required Parameters

  • gap_tempThe gap temperature variable name

    C++ Type:std::vector

    Description:The gap temperature variable name

  • distanceThe distance variable name

    C++ Type:std::vector

    Description:The distance variable name

  • execute_onTIMESTEP_ENDThe list of flag(s) indicating when this object should be executed, the available options include NONE, INITIAL, LINEAR, NONLINEAR, TIMESTEP_END, TIMESTEP_BEGIN, FINAL, CUSTOM.

    Default:TIMESTEP_END

    C++ Type:ExecFlagEnum

Optional Parameters

  • control_tagsAdds user-defined labels for accessing object parameters via control logic.

    C++ Type:std::vector

    Description:Adds user-defined labels for accessing object parameters via control logic.

  • enableTrueSet the enabled status of the MooseObject.

    Default:True

    C++ Type:bool

    Description:Set the enabled status of the MooseObject.

  • allow_duplicate_execution_on_initialFalseIn the case where this UserObject is depended upon by an initial condition, allow it to be executed twice during the initial setup (once before the IC and again after mesh adaptivity (if applicable).

    Default:False

    C++ Type:bool

    Description:In the case where this UserObject is depended upon by an initial condition, allow it to be executed twice during the initial setup (once before the IC and again after mesh adaptivity (if applicable).

  • use_displaced_meshTrueWhether or not this object should use the displaced mesh for computation. Note that in the case this is true but no displacements are provided in the Mesh block the undisplaced mesh will still be used.

    Default:True

    C++ Type:bool

    Description:Whether or not this object should use the displaced mesh for computation. Note that in the case this is true but no displacements are provided in the Mesh block the undisplaced mesh will still be used.

  • outputsVector of output names were you would like to restrict the output of variables(s) associated with this object

    C++ Type:std::vector

    Description:Vector of output names were you would like to restrict the output of variables(s) associated with this object
