Homogeneous-Heterogeneous Chemical Reactions of Radiation Hybrid Nanofluid Flow on a Cylinder with Joule Heating: Nanoparticles Shape Impact

The current analysis aims to exhibit the nanoparticles of Al2O3 + Cu-water hybrid nanofluid flow for Darcy-Forchheimer with heterogeneous-homogeneous chemical reactions and magnetic field aspects past a stretching or shrinking cylinder with Joule heating. This paper performed not only with the hybrid nanofluid but also the shape of Al2O3 and Cu nanoparticles. The model of single-phase hybrid nanofluid due to thermophysical features is utilized for the mathematical formulation. In the present exploration equal diffusions factors for reactants and auto catalyst are instituted. The system of governing equations has been simplified by invoking the similarity transformation. The numerical computations are invoked due to the function bvp4c of Matlab, with high non-linearity. Numerical outcomes illustrated that; sphere shape nanoparticles presented dramatic performance on heat transfer of hybrid nanofluid movement; an opposite behavior is noticed with lamina shape. The local Nusselt number strengthens as the transverse curvature factor becomes larger. In addition, the homogeneous-heterogeneous reactions factors lead to weaken concentration fluctuation.

Automated summary

This study focuses on the performance of Al2O3 + Cu-water hybrid nanofluid flow in Darcy-Forchheimer, including the influence of different shapes of nanoparticles on heat transfer performance. Numerical results demonstrate that spherical nanoparticles have a significant impact on the heat transfer performance of the hybrid nanofluid, while lamina-shaped particles exhibit opposite behavior. Furthermore, the local Nusselt number increases as the transverse curvature factor becomes larger.
