SOLAR ENERGY ENCOURAGEMENT IN SOLAR HVAC USING EYRING-POWELL TERNARY-HYBRID NANOFLUID FLOW IN POROUS MEDIUM WITH CATTANEO-CHRISTOV HEAT AND MASS FLUXES

This study presents a new 3D mathematical model to analyze rotating Eyring-Powell ternary-hybrid nanofluid flow in solar HVAC systems. The study examines the flow of a mixture of tri-hybrid nanoparticles inserted into ethyl glycol over a stretching sheet through a porous medium. The model considers solar thermal radiation, activation energy impact, and boundary qualifications. Similarity variables are used to transform governing equations into a set of nonlinear coupled ordinary differential equations, which are solved numerically using the Runge-Kutta-Fehlberg approach in MAPLE 2022 software. The results are shown graphically to investigate the impacts of regulating parameters on skin friction, heat, and mass transfer. It is demonstrated that an increase in the Eyring-Powell fluid and rotation parameters increases radial skin friction. Furthermore, the temperature slip and relaxation time parameters tend to reduce the Nusselt number, while the radiation parameter boosts the Nusselt number. The use of ternary nanofluids results in the highest Nusselt numbers. The study has importance in engineering applications such as the dying of metals and extrusion processing.
