Comparative thermal transport mechanism in Cu-H2O and Cu-Al2O3/H2O nanofluids: numerical investigation

Abstract

Thermal efficiency in conventional nanoliquids and hybrid nanofluid is one of the potential areas of research nowadays and multifariously applicable in broad industrial and engineering zone. The hybrid nanofluids have their own importance due to their enhanced thermal conductivity and better conductor for heat transfer. Therefore, the comparative study is performed conventional, and hybrid nanofluids are synthesized by Cu and Al2O3 with water as a base solvent. The novel nonlinear thermal radiations effects are introduced in the constitutive model and then furnished the results for the flow regimes (velocity, thermal behavior, shear stresses and local Nusselt number) by varying the physical constraints. Further, it is executed that the hybrid nanoliquids have ultra-high thermal performance than simple nanoliquid due to the addition of Al2O3. Finally, validation of the study is performed by restricting our model to some physical constraints and found them in excellent agreement with previously published work.
