modelHeatExchangerDynamics
Test model for stratified tank with steady-state and dynamic heat exchanger balance
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This validation model compares two tank models. The only difference between
the two tank models is that one uses a dynamic energy balance, whereas
the other uses a steady-state energy balance for the heat exchanger.
The mass flow rate through the heat exchanger is varied from zero to
the design flow rate and back to zero to test the model under conditions in
which no water flows through the heat exchanger.
