<p>Lucia,</p>
<p>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.</p>

<p class="MsoNormal"><span><!-- o ignored --> </span></p>
<p class="MsoNormal"><span>The idea is to simulate the water-steam stream using the solar field. I have seen that there is the possibility to use a flash tank to separate water and steam in the TESS library. 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.<!-- o ignored --></span></p>

<p class="MsoNormal"><span>Could you explain me briefly how can I change the outlet pressure in the collector type? It is possible to define steam at the outlet using a control? Is there any example that I can use to start my simulation?<!-- o ignored --></span></p>
