Abstract: Current research proposes a model for assessing the flow properties and heat transmission from hybridized nanofluids to solar collectors (SCs). A theoretical investigation that was based on the application of alumina-water (Al 2 O 3 -H 2 O) conventional nanofluid and copper/alumina-water (Cu-Al 2 O 3 /H 2 O) hybrid nanofluid has been considered between two rotating plates in parabolic trough solar collector (PTSC). The Cattaneo–Christov model (CCM) for heat fluxing is used for the thermal boundary layer analysis. The impact of centripetal and Coriolis forces on the swirling flow has been considered. Adequate transformations are utilised for the conversion of the regulating partial differential equations (PDEs) into a group of dimensionless ordinary differential equations (ODEs). Dimensionless ODEs are then tackled by the Keller box method (KBM) in the MATLAB program. The basic concept of this study is to inspect the influences of change in substantial factors on velocities, temperature, and heat transmission rate for both Al 2 O 3 -H 2 O mono nanofluid (MNF) and Cu-Al 2 O 3 /H 2 O hybridized nanofluid (HBNF). The striking feature of the investigation is that the hybrid nanofluid Cu-Al 2 O 3 /H 2 O has a less frictional force and an elevated heat transmission rate (RHT) as assessed with the traditional nanoliquid Al 2 O 3 -H 2 O. Consequently, the rotating factor slows RHT on the surface. In this case study, HBNF is better than the mono NF as a thermal and electrical conductor.
