Description
This study investigates Casson fluid flow in a vertical channel within a magnetohydrodynamic (MHD) region, incorporating chemical reaction effects. The channel consists of two regions: one filled with an electrically conducting fluid and the other with a Casson fluid. The nonlinear coupled governing equations are solved using the perturbation method with a small perturbation parameter. The results are presented graphically to analyze the flow characteristics. This systematic analysis yields the velocity and temperature distributions, governed by key parameters such as the Grashof number (Gr), Hartmann number (M), Casson parameter (?), and chemical reaction rate, all of which critically influence the hydrodynamic and thermal behavior of the system. It is observed that the larger the values of the viscosity ratio, width ratio, and the conductivity ratio, the larger the flow field. The findings reveal that the presence of Casson fluid enhances the thermal and mass Grashof numbers, attributed to buoyancy forces. Conversely, the chemical reaction parameter and Hartmann number exhibit a suppressive effect on the flow. The Author(s) under exclusive license to Universitdegli Studi di Ferrara 2026.
