Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This tank has the same geometric variables as TankWith3InletOutletArrays plus the feature of a HeatPort and the possibility of evaporation. (Assumption: The gas is condensed immediately afterwards so that a liquid boiling fluid is created.)
The tank can be initialized with the following options:
- GuessValues: no explicit initial conditions
- InitialValues: initial values of temperature (or specific enthalpy), composition and level are specified
- SteadyStateHydraulic: initial values of temperature (or specific enthalpy) and composition are specified; the initial level is determined so that levels and pressure are at steady state.
Full steady state initialization is not supported, because the corresponding initial equations for temperature/enthalpy are undetermined (the flow rate through the port at steady state is zero).
