Effect of Buoyancy, Velocity Power Index and Magnetohydrodynamics (MHD) Heat and Mass Transfer of Second-Grade Nanofluid flow over a Stretching-Porous Sheet with Chemical Reaction

Abstract

The second-grade plays a significant effect on the velocity of fluid knowing that
it possesses a characteristic of non-Newtonian fluid having the velocity field
with two derivatives in stress strain tensor relationship. In this study, the
combined effects of buoyancy forces, velocity index and
Magnetohydrodynamics (MHD) heat and mass transfer of second-grade
nanofluid flow over a stretching-porous sheet with chemical reaction is
considered. The nanofluid being examined in this study is the Copper (Cu) with
water (H2O) as the base fluid. The partial differential equations governing of
the flow are non-dimensionalized, transformed using the stream function and
the similarity variables. Hence, solved numerically using the mid-point
Richardson extrapolation code in MAPLE 2021 for various values of the
controlling parameters of the flow. The results are presented in graphs and
tables. From the study, it is observed that the increase in the buoyancy due to
temperature parameter (
