FlowDevice	(	shared_ptr< ReactorBase >	r0,
		shared_ptr< ReactorBase >	r1,
		const string &	name = `"(none)"`
	)

Member Function Documentation

◆ type()

string type ( ) const

inlineoverridevirtual

String indicating the connector implemented.

Usually corresponds to the name of the derived class.

Reimplemented from ConnectorNode.

Reimplemented in MassFlowController, PressureController, and Valve.

Definition at line 31 of file FlowDevice.h.

◆ massFlowRate()

double massFlowRate ( )

inline

Mass flow rate (kg/s).

Definition at line 36 of file FlowDevice.h.

◆ updateMassFlowRate()

virtual void updateMassFlowRate ( double time )

inlinevirtual

Update the mass flow rate at time 'time'.

This must be overloaded in subclasses to update m_mdot.

Reimplemented in MassFlowController, PressureController, and Valve.

Definition at line 47 of file FlowDevice.h.

◆ outletSpeciesMassFlowRate()

double outletSpeciesMassFlowRate ( size_t k )

Mass flow rate (kg/s) of outlet species k.

Returns zero if this species is not present in the upstream mixture.

Definition at line 109 of file FlowDevice.cpp.

◆ enthalpy_mass()

double enthalpy_mass ( )

specific enthalpy

Definition at line 121 of file FlowDevice.cpp.

◆ install()

bool install	(	ReactorBase &	in,
		ReactorBase &	out
	)

Install a flow device between two reactors.

Parameters

in	Upstream reactor.
out	Downstream reactor.

Deprecated:: To be removed after Cantera 3.2. Reactors should be provided to constructor instead.

Definition at line 48 of file FlowDevice.cpp.

◆ ready()

virtual bool ready ( )

inlinevirtual

Definition at line 65 of file FlowDevice.h.

◆ in()

ReactorBase & in ( ) const

inline

Return a reference to the upstream reactor.

Definition at line 70 of file FlowDevice.h.

◆ out() [1/2]

const ReactorBase & out ( ) const

inline

Return a const reference to the downstream reactor.

Definition at line 75 of file FlowDevice.h.

◆ out() [2/2]

ReactorBase & out ( )

inline

Return a mutable reference to the downstream reactor.

Definition at line 80 of file FlowDevice.h.

◆ evalPressureFunction()

double evalPressureFunction ( )

Return current value of the pressure function.

The mass flow rate [kg/s] is calculated given the pressure drop [Pa] and a coefficient set by a flow device specific function; unless a user-defined pressure function is set, this is the pressure difference across the device. The calculation of mass flow rate depends to the flow device.

Since: New in Cantera 3.0.

Definition at line 87 of file FlowDevice.cpp.

◆ setPressureFunction()

void setPressureFunction ( Func1 * f )

virtual

Set a function of pressure that is used in determining the mass flow rate through the device.

The evaluation of mass flow depends on the derived flow device class.

Reimplemented in MassFlowController.

Definition at line 82 of file FlowDevice.cpp.

◆ evalTimeFunction()

double evalTimeFunction ( )

Return current value of the time function.

The mass flow rate [kg/s] is calculated for a Flow device, and multiplied by a function of time, which returns 1.0 unless a user-defined function is provided. The calculation of mass flow rate depends on the flow device.

Since: New in Cantera 3.0.

Definition at line 101 of file FlowDevice.cpp.

◆ setTimeFunction()

void setTimeFunction ( Func1 * g )

virtual

Set a function of time that is used in determining the mass flow rate through the device.

The evaluation of mass flow depends on the derived flow device class.

Reimplemented in PressureController.

Definition at line 96 of file FlowDevice.cpp.

◆ setSimTime()

void setSimTime ( double time )

inline

Set current reactor network time.

Since: New in Cantera 3.0.

Definition at line 117 of file FlowDevice.h.

◆ ConnectorNode() [1/2]

ConnectorNode ( const string & name = "(none)" )

inline

Transitional constructor.

Todo:: Implement deprecation warning.

Definition at line 32 of file ConnectorNode.h.

◆ ConnectorNode() [2/2]

ConnectorNode	(	shared_ptr< ReactorBase >	r0,
		shared_ptr< ReactorBase >	r1,
		const string &	name = `"(none)"`
	)

inline

Instantiate a ConnectorNode object with associated ReactorBase objects.

Parameters

r0	First reactor.
r1	Second reactor.
name	Name of the connector.
