Abstract

The motivation for studying nanofluid behavior under the influence of various external forces stems from its numerous applications in a variety of engineering industries. This paper focuses on the effect of a magnetic field and heat flux on a Shrinking / Stretching Sheet in a base fluid. Nonlinear partial differential equations (PDEs) are reduced to nonlinear ordinary differential equations (ODEs) via a
similarity transformation, which are then numerically solved for two types of nanoparticles, namely copper and alumina, in the water-based fluid using the shooting technique. Considering the steady two-dimensional stagnation-point flow of a water-based nanofluid over a stretching/shrinking sheet. For some of the governing parameters of Grashof number (Gr), magnetic field (M), Prandtl number
(Pr), and volume fraction ( ), the velocity and temperature profiles were presented graphically and thoroughly discussed. It found that magnetic parameters and Grashof number solutions for a shrinking/stretching sheet increase velocity while decreasing temperature.
