Evaluating the Effects of Cu-Water Nanofluid, Space/Temperature Dependent Heat Source/Sink on Magnetohydrodynamics (MHD) Heat and Mass Transfer Stretching sheet with Buoyancy Forces

Abstract

Magnetohydrodynamics (MHD) heat and mass transfer with nanofluid flow has
attracted several authors in science, engineering and several fields of endeavour.
Several Newtonian and non-Newtonian fluids experiences friction in the course of
motion due to the presence of viscous forces. The flow of Cu-water nanofluid
volume fraction with the combine effects of space, temperature dependent heat
source/sink and buoyancy forces is considered in this study. The governing
equation is transformed from partial differential to ordinary differential using the
stream function and the similarity variables and solved numerically using solved
numerical using the mathematical package called the Mid-point Richardson
extrapolation code in MAPLE 2021. Hence, results are shown in tables and graphs
for various increasing values of the governing parameters. It is revealed from the
result of the study that the increase in the second-grade parameter (α) results in
the increase of the fluid velocity, The increasing function of the volume fraction (φ)
brings about the increase in the fluid motion and in the temperature of the fluid at
free stream, the increase in the space and temperature dependent heat source/sink
parameters A and B respectively result to the increase in the of the temperature at
the free stream and decrease in the concentration of the fluid and the increase in
the yields result to increase in the motion, temperature and concentration of the
fluid.
