Abstract
This paper discusses a Modelica library of switching moving boundary
models for two-phase flow heat exchangers: evaporators and condensers.
The equationbased object-oriented modeling paradigm has been
considered by means of designing basic models applying the conservation
laws for each flow state: subcooled liquid, two-phase flow and
superheated vapor. Evaporator and condenser models have been developed
by interconnecting the basic models and including mechanisms to switch
between different configurations: general, flooded and dry evaporators
and condensers. Finally, simulation results are presented by an
integrity and stability test case.
