Information

This is a model for a fluid boundary condition with fixed

  • mass flow rate
  • temperature
  • composition

Modelling options

The actual gas used in the component is determined by the replaceable Medium package. In the case of multiple component, variable composition gases, the nominal gas composition is given by X0,whose default value is Medium.reference_X .

If the mdot_in connector is wired, then the source massflowrate is given by the corresponding signal, otherwise it is fixed to m_flow0.

If the T_in connector is wired, then the source temperature is given by the corresponding signal, otherwise it is fixed to T0.

If the X_in connector is wired, then the source massfraction is given by the corresponding signal, otherwise it is fixed to X0.
