Flowrate source for water/steam flows

Information

Modelling options

If G is set to zero, the flowrate source is ideal; otherwise, the outgoing flowrate decreases proportionally to the outlet pressure.

If use_T is false, the specific enthalpy is prescribed, otherwise the temperature is prescribed.

The mass flow rate, specific enthalpy and temperature can be supplied from external inputs by setting to true the corresponding use_in_XX parameter and connecting an external signal to the input connector.

Parameters

Type	Name	Default	Description
Medium.MassFlowRate	w0	0	Nominal mass flowrate
Medium.AbsolutePressure	p0	1e5	Nominal pressure
Units.HydraulicConductance	G	0	Hydraulic conductance
Boolean	use_T	false	Use the temperature if true, otherwise use specific enthalpy
