Member Function Documentation

◆ type()

virtual string type ( ) const
inlinevirtual

String indicating the flow device implemented.

Usually corresponds to the name of the derived class.

Reimplemented in MassFlowController, PressureController, and Valve.

Definition at line 34 of file FlowDevice.h.

◆ massFlowRate()

double massFlowRate ( )
inline

Mass flow rate (kg/s).

Definition at line 39 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 50 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 72 of file FlowDevice.cpp.

◆ enthalpy_mass()

double enthalpy_mass ( )

specific enthalpy

Definition at line 84 of file FlowDevice.cpp.

◆ install()

bool install ( ReactorBase in,
ReactorBase out 
)

Install a flow device between two reactors.

Parameters
inUpstream reactor.
outDownstream reactor.

Definition at line 14 of file FlowDevice.cpp.

◆ ready()

virtual bool ready ( )
inlinevirtual

Definition at line 66 of file FlowDevice.h.

◆ in()

ReactorBase & in ( ) const
inline

Return a reference to the upstream reactor.

Definition at line 71 of file FlowDevice.h.

◆ out()

const ReactorBase & out ( ) const
inline

Return a const reference to the downstream reactor.

Definition at line 76 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 50 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 45 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 64 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 59 of file FlowDevice.cpp.

◆ setSimTime()

void setSimTime ( double  time)
inline

Set current reactor network time.

Since
New in Cantera 3.0.

Definition at line 113 of file FlowDevice.h.
