Test model for expansion vessel

Annex60.Fluid.Storage.Examples.ExpansionVessel

Information

This model tests a pressure expansion vessel. The medium model that is used in this example changes its density as a function of temperature. To see the effect of the expansion vessel, delete the connecting line between the volume and the expansion vessel and check how much more the pressure increases as the fluid is heated.
