Exploring the marvels of heat transfer: MHD convection at a stagnation point in non-Newtonian fluid with yield stress and chemical reactions

This study uses a non-Newtonian fluid with yield stress to investigate the complex dynamics of heat transmission in a stagnation-point MHD (Magnetohydrodynamic) convection system. The Casson fluid flow is used to model the fluid's behaviour, and for analytical tractability, the governing partial differential equations (PDEs) are converted into ordinary differential equations (ODEs). The RK-Fehlberg method is used to obtain the numerical solution. The study's main outcomes include the effects of magnetic field strength on the temperature, flow fields and the complex correlations that are shown between the Casson fluid parameters and heat transfer properties. Furthermore, the study highlights the mutually reinforcing impacts of thermal radiations and chemical processes on the heat transfer process. The study offers important insights for applications in a variety of domains, from materials science to environmental engineering, and advances our understanding of the linked impacts of magnetic fields, non-Newtonian behaviour, and chemical reactions on heat transport phenomena.
