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).
