Absorptance reduction

Hi,

The absorptance is considered independent from the incidence angle or it is reduced by a curve? In that case, which is the reduction curve?

Thanks

Hello,

Please provide more detail about the model you are using and the specific variable you are asking about. There are several different models in SAM that use that variable.

Best regards,
Paul.

Sorry, I am asking about the molted salt model with in the tower and receiver, the coating absortance.

Thank you for the clarification. Please see the discussion on p. 29 of Wagner, M. (M.S. 2008). "Simulation and Predictive Performance Modeling of Utility-Scale Central Receiver System Power Plants." University of Wisconsin-Madison. ( ZIP 32.3 MB )
Best regards,
