Significance of MHD Micropolar Tri-hybrid Nanofluid Flow past a Stretched Surface with Modified Fourier and Fick's law

Abstract

Abstract 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.
