Nonlinear Solar Thermal Radiation Efficiency and Energy Optimization for Magnetized Hybrid Prandtl-Eyring Nanoliquid in Aircraft

A rising demand for industrial expansion, and optimization of energy and cost have stimulated researchers to consider effective usages of solar radiation and nanomaterials. As such, this study focuses on the flow rate, thermal distribution and entropy generation of the magnetized hybrid Prandtl-Eyring nanofluid flow along the interior parabolic solar trough collector of an aircraft wing. A nonlinear solar radiation and Joule heating of the aircraft wings, and the hybridization of cobalt ferrite (CoFe2O4) and copper (Cu) nanoparticles are considered in an ethylene glycol (EG) base fluid. The transformed nonlinear coupled mathematical model for the hybrid Prandtl-Eyring nanofluid flow in a boundless medium with jump temperature and convective cooling boundary conditions is analytically solved. The flow dimensions and the engineering factors (shear stress and heat gradient) for various thermofluid parameter sensitivities are examined and comprehensively reported. As found, the CoFe2O4-Cu/EG nanofluid has high thermal conductivity than the Cu-EG nanofluid. It is revealed that the energy optimization of the system is upsurged by encouraging phi, phi(hnf) nanoparticle volume fraction. Hence, the study will benefit the thermal engineering for an advanced nanotechnology and solar aircraft efficiency.
