This research explores the linear and nonlinear radiation patterns of MHD non-Newtonian (Maxwell) nanofluid flow with Arrhenius activation energy. The study focuses on MHD properties in non-Newtonian fluid dynamics and boundary layer phenomena, using time-dependent equations and boundary layer approximations. Numerical computations, performed with custom Compact Visual Fortran code and the EFD method, provide insights into non-Newtonian fluid behavior, revealing intricate force interactions and fluid patterns. The stability of the solution is checked through convergence and stability analysis, with the model converging for Lewis number (Le) > 0.016 and Prandtl number (Pr) > 0.08. The effects of various physical parameters on temperature, concentration, and velocity profiles are visualized, and the skin friction coefficient, Sherwood number, and Nusselt values are discussed. The study highlights the superior performance of non-Newtonian solutions, particularly in cases involving activation energy and nonlinear radiation, with significant implications for applications in medicine and industry, such as cancer treatment. The interplay between Maxwell fluid and nonlinear radiation is notably affected by activation energy, offering promising applications in fields like medicine and industry.This research explores the linear and nonlinear radiation patterns of MHD non-Newtonian (Maxwell) nanofluid flow with Arrhenius activation energy.
