Abstract
Most concentrated thermal solar power uses convectional liquids as its working fluid for power generation. These fluids have a low heat conduction strength that cannot keep up with the present industrial and thermal technology demands. Meanwhile, nanomaterials have been established as good heat conductors and propagators for an enhanced thermal system. As such, this study considers electromagnetic Williamson fluid combined with water+ethylene-glycol (H2O+C2H6O2) solvent for thermal migration of Fe3O4 and SiO2 metallic oxide nanoparticles and a nonlinear radiation absorber for concentrated thermal power maximization. A transformed invariant model from the developed nonlinear boundary value partial derivative equations governing the thermofluid is obtained via similarity variables. This model is solved by Chebyshev spectral collocation method to determine the sensitivity of the flow dimensions. The investigations revealed that a decreased in the current density magnified the heat transfer, and electromagnetic field enhanced the hybrid nanofluids thermal power generation. Hence, the terms that enhanced heat transfer should be monitored to present thermal system blowup.
