This work presents an in-depth examination of heat and mass transfer phenomena in a radiative and chemically reactive magneto-micropolar nanofluid flow under the influence of convective boundary conditions. The governing equations of the model, represented in their non-linear form via Falkner and Skan transformations, are scrutinized using the Finite Element Method (FEM). Validation with existing literature corroborates the precision of the proposed model. Analyses of the results elucidate the impacts of various parameters on the temperature, species concentration, micro-rotation, and velocity characteristics of the system. Notably, an enhancement in the thermal conductivity of the magneto-micropolar nanofluid is observed in correlation with an increased nanoparticles volume fraction. A positive relationship is discerned between the temperature and the parameters for radiation and convective boundary conditions. Furthermore, a decrement in the Schmidt number is associated with an accelerated diffusion rate. The findings derived from this study hold substantial implications for practical applications in diverse fields such as heat and cooling systems, enhanced oil recovery, thermal management in electronics, material processing, and nanofluidics. This research thus contributes to the existing body of knowledge by offering an intricate understanding of the behavior and manipulation of magnetomicropolar nanofluid flow.

The present study assesses the constant surface heat flux on a 2D steady convective flow of a micropolar fluid. The flow occurs along a vertical impermeable flat plate immersed in a fluid‐saturated porous medium. Numerical methods are used to convert the governing partial differential equations to gather the locally equivalent ordinary differential equations. Local similarity solutions also visually depict the velocity distribution and microrotation (ω) in the boundary layer. Furthermore, the influence of the physical variables on the flow field is investigated. The numerical results show that the effect of porosity (ε) on the velocity profile demonstrates a negative correlation between ε and velocity. The correlation between microrotation (ω) involving the ε influence also depends on the similarity parameter (η). Although microrotation (ω) increases with porosity (ε) in the region where the fluid is near the surface, this trend changes as the flow moves further away from the surface. The dimensionless microrotation (ω) value remains constant, while rotation is not observed for the similarity parameter (η) values exceeding 4.5. The value of microrotation (ω) value is small for the similarity parameter (η) values in the interval (0 < η < 1.4). Nonetheless, the microrotation (ω) value is high for the similarity parameter (η) values up to η = 4.5. Therefore, the point at η = 1.4 represents a crucial point in the present study. The results of the present study have been validated, and the comparison with related articles showed an excellent matching between results. Outcomes from the current study are very beneficial to enhance the performance of solar panels by improving the cooling of such panels.
