Significance of non-linear radiative flux in thermal and entropy optimization of hybrid Casson nanofluid over a spinning permeable sphere

Transmission of energy in flow over spinning sphere or rotating objects has outstanding utilization in various engineering and scientific disciplines. For instance, reactors safety, aerosol cooling, heat exchangers, lubrication, water contaminants removal and many more. So, taking motivation from these applications, a multipurpose investigation to optimize energy proficiency by adding amalgamation of Penta-hybridized nanoparticles in viscoelastic material flow over a rotating sphere is adhered in current artifact. Effectiveness of periodically variant magnetic field instead of considering it uniformly has been employed to make problem more realistic to real world applications. To explore hydrothermal attributes of flow accounted in domain, Casson rheological model is introduced. Catalytic reactions subjected to homogeneity/heterogeneity has been used to enhance exchange in energy among fluid layers. Mathematical formulation of problem concerned with empirical relations of considered nanocomposites along with physical factors is modelled in the form of ordinary differential setup after using similarity approach. Numerical simulations are performed by using finite element method. Results are drawn in the view of pictorial and tabulated formats.
