The Stagnation Point Flow of the MHD Casson Polymeric Nanofluid Flows Toward a Wavy Circular Cylinder Saturated with a Porous Medium under Convective Nield Conditions and Thermal Radiation

This study conducts a thorough numerical investigation employing the bvp4c technique to delve into the stagnation-point flow of a magnetohydrodynamic (MHD) Casson polymeric nanofluid around a wavy circular porous cylinder. It takes into account activation energy and thermal radiation, emphasizing the significant impact of thermal radiation on fluid flow, concentration and temperature profiles. The effects of thermal radiation within the energy equation are carefully considered, along with convective Nield boundary conditions, enabling a comprehensive analysis. By introducing dimensionless variables, the study transforms the partial differential equation into ordinary equations, facilitating the application of the shooting scheme to approximate the solution. The meticulously examined results offer detailed insights into temperature, velocity and mass concentration profiles, highlighting the profound influence of thermal radiation on these parameters. Furthermore, a comprehensive graphical presentation of each engineering parameter is provided, offering a nuanced understanding of the intricate physical phenomena involved, with particular attention to the influence of thermal radiation.
