Radiative heat transport of cattaneo-christov double diffusive casson nanofluid flow between two rotating disks with hall current and activation energy

The present research uncovers the mathematical exploration of the magnetohydrodynamic radiative Casson nanofluid flow produced due to stretching and coaxially rotating surfaces of two disks inside a non-Darcy porous medium under the dominance of the diacritic Hall current and heat generation. The energy field is displayed under the dominance of radiative and dissipative heat transport by involving the consequences of distinctive nonlinear thermal radiation, viscous dissipation, and Joule heating. The present study overcomes the barrier of heat and mass transport by annexing Cattaneo-Christov double diffusion effects. The current exploration shows the characteristics of the concentration field due to arising chemical reaction incited by activation energy. A substantive mathematical problem is modeled by assigning nonlinear partial differential equations together with convective boundary conditions. A compatible similarity transformation comprised in the current study is exerted to produce a set of nonlinear ordinary differential equations with competent boundary conditions. The resulting mathematical model is numerically solved via dispensing the SLM. The present article deals with an in-depth exploration of diagnostic flow parameters' attributes against the flow field and efficient physical quantities with the help of distinctive graphs and tables. As per the current investigation, the energy field becomes potent due to enhancing the stretching of each of the disks. Besides, augmenting the thermophoretic diffusion and chemical reaction boosts diluting the concentration of nanoparticles. The flow along the radial direction gets controlled near the upper disk under the increasing influence of the Hall current, intensity of the magnetic field, and stretching rate of the lower disk. On the other hand, the enlarging Casson parameter, rotation parameter, and stretching parameter for the lower disk lead to controlling the flow along the radial direction adjacent to the lower disk. Apart from that, the intense effects of the stretching rate of the upper disk and rotation rein axial flow throughout the flow region.

Automated summary

The present research investigates the mathematical exploration of magnetohydrodynamic radiative Casson nanofluid flow and explores the effects of different parameters on the flow characteristics. The study reveals that stretching and chemical reaction enhance the energy field, while thermophoretic diffusion and chemical reaction decrease the concentration of nanoparticles. In the radial direction, flow near the upper disk is controlled by the Hall current, magnetic field intensity, and stretching rate of the lower disk. On the other hand, the Casson parameter, rotation parameter, and stretching parameter for the lower disk control the flow along the radial direction near the lower disk. The stretching rate of the upper disk and rotation enhance axial flow throughout the flow region.
