Information

The actual gas used in the component is determined by the replaceable GasModel model. In the case of multiple component, variable composition gases, the nominal gas composition is given by Xnom, whose default value is Medium.reference_X .

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

If the in_w0 connector is wired, then the source massflowrate is given by the corresponding signal, otherwise it is fixed to w0.

If the in_T connector is wired, then the source temperature is given by the corresponding signal, otherwise it is fixed to T.

If the in_X connector is wired, then the source massfraction is given by the corresponding signal, otherwise it is fixed to Xnom.
