摘要/Abstract

摘要： This paper presents the buoyancy effects on the magneto-hydrodynamics stagnation point flow of an incompressible, viscous, and electrically conducting nanofluid over a vertically stretching sheet. The impacts of an induced magnetic field and viscous dissipation are taken into account. Both assisting and opposing flows are considered. The overseeing nonlinear partial differential equations with the associated boundary conditions are reduced to an arrangement of coupled nonlinear ordinary differential equations utilizing similarity transformations and are then illuminated analytically by using the optimal homotopy investigation strategy (OHAM). Graphs are introduced and examined for different parameters of the velocity, temperature, and concentration profile. Additionally, numerical estimations of the skin friction, local Nusselt number, and local Sherwood number are explored using numerical values.
