In this article, we investigate the bioconvection flow of Casson nanofluid by a rotating disk under the impacts of Joule heating, convective conditions, heat source/sink and gyrotactic microorganisms. When Brownian diffusion and thermophoretic effects exist, the Casson fluid is examined. The existing physical problem of Casson nanofluid flow with energy transports is demonstrated under the above considerations in the form of partial differential equations (PDEs).

Article Synopsis
  • The research examines entropy generation in a 2D magneto Williamson hybrid nanofluid flow that incorporates cobalt ferrite and titanium oxide nanoparticles, influenced by surface-catalyzed reactions.
  • It addresses the effects of factors like joule heating, viscous dissipation, thermal stratification, and thermal radiation, while transforming the problem into a dimensionless system of equations for analysis.
  • The study utilizes numerical solutions through MATLAB's bvp4c technique, comparing results with existing literature and finding that increased homogeneous reaction strength and surface-catalyzed parameters reduce concentration fields and affect velocity distribution.

It is still not quite apparent how suspended nanoparticles improve heat transmission. Multiple investigations have demonstrated that the aggregation of nanoparticles is a critical step in improving the thermal conductivity of nanofluids. However, the thermal conductivity of the nanofluid would be greatly affected by the fractal dimension of the nanoparticle aggregation.

To aid in the prevention of reaction explosions, chemical engineers and scientists must analyze the Arrhenius kinetics and activation energies of chemical reactions involving binary chemical mixtures. Nanofluids with an Arrhenius kinetic are crucial for a broad variety of uses in the industrial sector, involving the manufacture of chemicals, thermoelectric sciences, biomedical devices, polymer extrusion, and the enhancement of thermal systems via technology. The goal of this study is to determine how the presence of thermal radiation influences heat and mass transfer during free convective unsteady stagnation point flow across extending/shrinking vertical Riga plate in the presence of a binary chemical reaction where the activation energy of the reaction is known in advance.
