This research revealed control on nanofluid temperature in the evacuated tube solar collector system, where nanofluid used in ETSC as working fluid to increase heating system thermal efficiency. Smart curtain was used to shadow the evacuated tube solar collector in heating or cooling conditions to control the temperature of the nanofluid. Moreover, (PSO based PID) controller which is an artificial intelligence method was applied to control on the shadow the evacuated tube solar collector. Where the curtain's main idea is to control the polarization of the sun's radiation, the work of the curtain refers to the parameters: the first parameter is the nano fluid temperature and the second is the ambient temperature, and one output parameter is defined by (distance parameter).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
