Detailed Description
Supply a mass flow rate that is a function of the pressure drop across the valve.
The default behavior is a linearly proportional to the pressure difference. Note that real valves do not have this behavior, so this class does not model real, physical valves.

Member Function Documentation
◆ typeStr()
|
inlinevirtual |
String indicating the flow device implemented.
Usually corresponds to the name of the derived class.
Reimplemented from FlowDevice.
Definition at line 121 of file flowControllers.h.
◆ setPressureCoeff()
|
inline |
Set the proportionality constant between pressure drop and mass flow rate.
c has units of kg/s/Pa. The mass flow rate is computed as:
\[\dot{m} = c \Delta P \]
- Deprecated:
- To be removed after Cantera 2.5.
Definition at line 132 of file flowControllers.h.
References FlowDevice::m_coeff, and Cantera::warn_deprecated().
◆ setValveCoeff()
|
inline |
Set the proportionality constant between pressure drop and mass flow rate.
c has units of kg/s/Pa. The mass flow rate is computed as:
\[\dot{m} = c g(t) f(\Delta P) \]
where g and f are functions of time and pressure drop that are set by setTimeFunction and setPressureFunction, respectively. If no functions are specified, the mass flow rate defaults to:
\[\dot{m} = c \Delta P \]

◆ getValveCoeff()
|
inline |
Get the valve coefficient.
Definition at line 154 of file flowControllers.h.

◆ updateMassFlowRate()

Compute the currrent mass flow rate, based on the pressure difference.
