Hi,



I am having trouble setting up a simple solar thermal model.

I have a Parabolic Trough Collector, a hollow cylindrical copper receiver, and water as a heat transfer fluid inside that receiver, the simulation is for my university project.

I cannot seem to attain any significant temperature rise regardless of my set up parameters so I am obviously doing something wrong - can someone please help me with the set up?
