This research investigates the steady, electrically conducting flow of a micropolar nanofluid across a porous stretched surface at stagnation points. The mathematical model incorporates the effects of non-linear thermal radiation, convective heating, thermophoresis, and heat transfer. Using a similarity transformation, the governing partial differential equations are converted into a system of coupled, non-linear ordinary differential equations. These equations are solved numerically through a shooting method implemented in MATLAB using the bvp4c routine. The resulting calculations evaluate how key variables, including the magnetic parameter, slip parameter, Lewis number, Prandtl number, Brownian motion, and suction or injection velocity, affect the fluid velocity, micropolar rotation, temperature distribution, and nanoparticle concentration profiles.
Understanding how complex nanofluids behave under the influence of magnetic fields and thermal radiation helps researchers predict fluid movement and heat management in advanced engineering systems. These simulations offer detailed mathematical insights into the combined effects of particle rotation, chemical reactions, and porous boundaries on thermal energy transport.

In current study, the steady electrically conducting flow of micropolar nanofluid past a porous stretched surface across stagnation points is investigated. For motivation of problem, the impressions of the nonlinear thermal radiation and convectively heated have been analyzed. In additions, the influence of thermophoresis and heat transfer are the part of this study. The governing firm of PDEs are converted to a system of nonlinear and coupled ODEs using the similarity approach. Moreover, the resulting problem is numerically integrated with the aid of shooting approach by utilizing the bvp4c programmer of MATLAB. The numerical outcomes are calculated using various physical parameter values and contrasted with previously published results. Numerical values of the physical quantities like velocity, micropolar rotation, temperature and concentration profile for involving parameters such as Prandtl number Pr, radiation R, slip parameter α, thermophoresis Nt, suction/injection velocity fw, Brownian motion Nb, magnetic parameter M and Lewis number Le are also computed and deliberated in this consideration.
