This study presents a comprehensive analysis of the magnetohydrodynamic radiative flow of Casson fluid past a cylindrical surface with convective heat transfer, Ohmic heating, and chemical reactions. The findings have significant implications for various fields, including radiation therapy, pharmaceutical delivery, geomechanics, food safety, and more. Notably, convective boundary conditions play a crucial role in laser-induced damage and material processing. By adopting a non-dimensional approach, this research leverages the homotopy analysis method to derive analytical solutions for governing nonlinear ordinary differential equations, thereby elucidating the effects of key parameters on momentum, thermal and solutal transport. The buoyancy force parameter enhances fluid motion, while magnetic and Casson parameters reduce velocity. Ohmic heating and Biot number, conversely, increase temperature distributions. Our results show excellent agreement with existing studies, confirming their validity.
