Member Function Documentation

◆ type()

string type ( ) const
inlineoverridevirtual

String indicating the flow device implemented.

Usually corresponds to the name of the derived class.

Reimplemented from FlowDevice.

Definition at line 25 of file flowControllers.h.

◆ setMassFlowRate()

void setMassFlowRate ( double  mdot)

Set the fixed mass flow rate (kg/s) through the mass flow controller.

Definition at line 13 of file flowControllers.cpp.

◆ setMassFlowCoeff()

void setMassFlowCoeff ( double  m)
inline

Set the mass flow coefficient.

m has units of kg/s. The mass flow rate is computed as:

\[\dot{m} = m g(t) \]

where g is a function of time that is set by setTimeFunction. If no function is specified, the mass flow rate defaults to:

\[\dot{m} = m \]

Definition at line 40 of file flowControllers.h.

◆ getMassFlowCoeff()

double getMassFlowCoeff ( )
inline

Get the mass flow coefficient.

Definition at line 45 of file flowControllers.h.

◆ setPressureFunction()

void setPressureFunction ( Func1 f)
inlineoverridevirtual

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 from FlowDevice.

Definition at line 49 of file flowControllers.h.

◆ updateMassFlowRate()

void updateMassFlowRate ( double  time)
overridevirtual

If a function of time has been specified for mdot, then update the stored mass flow rate.

Otherwise, mdot is a constant, and does not need updating.

Reimplemented from FlowDevice.

Definition at line 21 of file flowControllers.cpp.
