“…Furthermore, Reddy et al 6 , studied the heat and mass transfer properties of hybrid nanofluid flowing over a flat surface subjected to stretching/shrinking. Santhi et al 7 implemented the double stratification model and compared the steady and unsteady flow of nanofluid. Meanwhile, Basha et al 8 studied the ferromagnetic stagnation flow of Carreau nanofluid over a wedge and observed a declination in the velocity for the stronger magnetic field.…”

The primary goal of this article is to explore the radiative stagnation point flow of nanofluid with cross-diffusion and entropy generation across a permeable curved surface. Moreover, the activation energy, Joule heating, slip condition, and viscous dissipation effects have been considered in order to achieve realistic results. The governing equations associated with the modeling of this research have been transformed into ordinary differential equations by utilizing appropriate transformation variable. The resulting system of equations was solved numerically by using Bvp4c built-in package in MATLAB. The impact of involved parameters have been graphically examined for the diverse features of velocity, temperature, and concentration profiles. Throughout the analysis, the volume fraction is assumed to be less than $$5\%$$ 5 % while the Prandtl number is set to be $$6$$ 6 . In addition, the entropy generation, friction drag, Nusselt, and Sherwood numbers have been plotted for describing the diverse physical aspects of the underlying phenomena. The major outcomes reveal that the curvature parameter reduces the velocity profile and skin friction coefficient whereas the magnetic parameter, temperature difference parameter, and radiation parameter intensify the entropy generation.

“…Effects of thermal radiation, viscous dissipation, and heat production / absorption on the MHD flow of a double-stratified nanofluid towards an exponentially stretched sheet were explored by Murugesan and Kumar [25]. In the existence of thermal and subatomic stratifications, magnetic field effects, and steady and unsteady MHD nanofluid flows, Snthi et al [26] investigation of the heat transmission analysis for these flows was conducted. They found that the greater estimates of thermal and solutal stratifications respectively lead to a degradation of the temperature and concentration profiles.…”

The present analysis focuses on a comprehensive study involving the synergistic exploration of diverse scientific concepts, encompassing micropolar trihybrid nanofluids, stagnation point flow, and second-grade fluids, with the use of expanded versions of the Fick's and Fourier's laws. Further, the influences of double stratification, viscous dissipation, activation energy, thermal radiation, and magnetohydrodynamics are incorporated. The research further extends to the implementation of the modified Fick's and Fourier’s laws, which provide a comprehensive framework for understanding heat-mass communication in such intricate systems. Using the proper similarity variables, the flow model equations are converted into their non-dimensional form. These transfer version equations are numerically resolved using MATLAB implementation of the BVP4C technique. For several emerging dimensionless parameters, the graphical and numerical results are derived and analysed. From the figures, clearly, with larger values of the 2nd -grade fluid parameters, the fluid velocity and temperature flow rapidly with the presence of ternary hybrid nanofluid in comparison to unary nanofluid.
