Rigid adiabatic volume
Extends from Icons.Gas.Mixer.
Information
This model describes a rigid, adiabatic control volume.
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 start composition is given by Xstart, whose default value is Medium.reference_X .
