modelTwoPhaseSeparator
Test model to show the functionality of the two-phase seperator
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This is a simple example model to test the two-phase separator model. Therefore, the tank's temperature at inlet is a function of time as well as the tank's pressure at outlet. The time dependencies of temperature and pressure leads to changes of steam quality at inlet and outlet conditions as well as the tank's mean steam quality.
Suggestions
Although the two-phase separator works for water introduced as two-phase medium (e.g. WaterIF97_phy), it is recommended to use refrigerants as working fluids.Parameters
