Mixed Convective-Radiative Dissipative Magnetized Micropolar Nanofluid Flow over a Stretching Surface in Porous Media with Double Stratification and Chemical Reaction Effects: ADM-Padé Computation

The present study deals with the electrically conducting micropolar nanofluid flow from a vertical stretching surface adjacent to porous medium under transverse magnetic field. Eringen’s model is deployed for non-Newtonian characteristics and Buongiorno employed nanoscale effects (thermophoresis Brownian motion). includes double stratification (thermal solutal) also chemical reaction effects, heat source, viscous dissipation. Darcy’s Rosseland diffusion flux approximation nonlinear thermal radiation. governing partial differential conservation equations are rendered into ordinary via relevant transformations. An innovative semi-numerical methodology combining Adomian decomposition method (ADM) Padé approximants known as ADM-Padé solve emerging boundary value problem appropriate wall free stream conditions in MATLAB software. A detailed parametric of influence key parameters on function, velocity, microrotation (angular velocity), temperature, nanoparticle concentration profiles conducted. Furthermore, skin friction coefficient, couple stress Nusselt number, Sherwood number displayed tables. validation both numerical techniques used, i.e., ADM ADM-Padé, against conventional 4th order Runge–Kutta included significant acceleration convergence solutions achieved approach. decelerated greater buoyancy ratio parameter whereas velocity) enhanced. Increasing solutal suppresses microrotation. Concentration magnitudes boosted Lewis number. Temperatures significantly enhanced radiative parameter. motion depletes values. finds applications thermomagnetic coating processes involving nanomaterials microstructural characteristics.
