Information

The SolarCollectorIncSchott model is based on the same modeling concept of the SolarCollector model.

The dynamic one-dimensional radial energy balance around the heat collector element is based on the Schott test analysis using the AbsorberSchott model.

The heat transfer fluid in this case is considered incompressible and so the Flow1DimInc is used.
