[TRNSYS-users] TRNSYS Simulation Fresnel & steam

[Jeff Thornton]

Lucia, 

The collector models that you reference are not intended to work with
two-phase flow like steam and were written assuming constant liquid
inlet and outlet fluid properties. Have you considered keeping the
collector loop isolated from the steam loop and utilizing a steam
generator to create the steam? Many of the large solar power plants
utilize this concept.

In this tank, it is possible to define the pressure. However, I have seen that in the solar collector field it is not possible to fix the outlet pressure, only the Cp can be modified.
