Analytical Investigation of Magnetic Field on Unsteady Boundary Layer Stagnation Point Flow of Water-Based Graphene Oxide-Water and Graphene Oxide-Ethylene Glycol Nanofluid over a Stretching Surface

This study explains the effect of magnetic field stagnation point flow a water-based nanofluid graphene oxide-water (GO-W) and oxide-ethylene glycol (GO-EG). Heat transfer analyses are discussed by converting given partial differential equation into nonlinear ordinary using similarity transformation solved an approximate analytical method, namely, optimal homotopy analysis method (OHAM), to obtain solution problem that analyzes problem. The BVPh 2.0 package function Mathematica is used numerical results. results important parameters such as parameter, unsteady stretching Prandtl number, Eckert kinematic parameter for both velocity temperature profiles plotted discussed. convergence control obtained up 25th iteration package. skin friction coefficient Nusselt number explained in tabular form.
