Detailed Description

Valve objects 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

virtual void updateMassFlowRate ( doublereal time )

inlinevirtual

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

Reimplemented from FlowDevice.

Definition at line 114 of file flowControllers.h.

References Func1::eval(), FlowDevice::in(), and FlowDevice::out().

doublereal massFlowRate ( double time = -999.0 )

inlineinherited

Mass flow rate (kg/s).

Definition at line 65 of file FlowDevice.h.

doublereal outletSpeciesMassFlowRate ( size_t k )

inherited

Mass flow rate of outlet species k.

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

Definition at line 56 of file FlowDevice.cpp.

Setpoint.

Default = 0.0. Set the setpoint. May be changed at any time. By default, this does nothing. Set the controller gains. Returns false if the number of gains is too small, or if an illegal value is specified. Get the controller gains. Returns false if the 'gains' array is too small. Maximum difference between input and setpoint since last call to 'reset'. Install a flow device between two reactors.
