modelFluidStorageChargeDischargeProfile
Example that demonstrates the charging / discharging process with different number of layers in the thermal storage
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
Charges storage of 1 m³ from the top with increasing temperature for 1000 s at 1 kg/s. After 1 h, discharges the for same duration at the same rate.
Different storage discretizations show different results, e.g. HRF.
