The complicated interaction of fluid motion with curved surfaces has a considerable impact on flow dynamics, resulting in diverse patterns and occurrences. A key phenomenon in many engineering fields is fluid flow on curved geometries. In both nature and industry, curved surfaces which are distinguished by their continuous curvature are used in everything from hydroelectric power plants and healthcare equipment to aerodynamic wing designs. This research aims to consider microfluid flow and heat transfer using magnetohydrodynamics via a curved surface. This study also delineates the several critical factors like viscous dissipation and thermal stratification. The model explores how an external magnetic field and stratified heat generation, where heat varies spatially, can be used to precisely control micropolar fluid flow in realistic thermal environments. By analysing the combined effects of magnetic forces, microrotation, thermal stratification and viscous dissipation the study offers insights applicable to advanced thermal systems in cooling systems, magnetic drug delivery, and materials processing. The laws of momentum, and energy conservation serve as the foundation for the problem mathematical formulation. Appropriate transformation techniques are exerted to reduce the complexity of the governing partial differential equations and remodelled into ordinary differential equation. Solutions are derived numerically by employing MATLAB’S built-in boundary value problem 5C function and are illustrated graphically. The results reveal that the temperature decays for stratification parameter. This behaviour is due to the temperature differential between the sheet and the surrounding fluid. Also, the microrotation grows for material parameter. These results suggest that the proposed model play significant role in thermal managements.
