Abstract

The growing demand for increased heat conduction in thermal science-based fluids for better industrial performance and engineering applications has sparked substantial interest. This study looks at how internal heat generation affects the mixed convection flow of a micro polar nano fluid over an exponentially stretched plate, taking into account the Brownian motion parameter and the Prandtl number. The semi-analytical Galerkin weighted residual approach is used to solve a nonlinear ordinary differential equations (ODE) system. The Galerkin technique is used iteratively to evaluate various parameter values, with all computations carried out in the Maple software environment for accuracy. Graphical representations reveal how critical parameters influence the temperature, velocity, concentration, and motion fields within the boundary layer. The Sherwood and Nusselt numbers, as well as the local skin friction coefficients, are tabulated. The findings are validated and highlighted as significant by comparing them to current literature.
