Analysis of GO-MoS2/EG Powell-Eyring Fluid Transportation in Stagnation Point Flow and Heat Transfer over a Shrinking Surface

Abstract

Using ethylene glycol as the base fluid, nanomaterials graphene oxide (GO) and molybdenum disulfide (MoS₂) are disseminated into the fluid. The heat transfer behaviour of a non-Newtonian Powell-Eyring fluid hybrid nanofluid is evaluated together with several effects such as magnetic, suction and radiation. Ordinary differential equations (ODEs) are acquired by deriving the mathematical model in partial differential equations (PDEs) with suitable similarity transformations. The formulas are numerically estimated with the assistance of the bvp4c solver in MATLAB. The impact of parameter effects on the skin friction coefficient, local Nusselt number, entropy generation, velocity profile and temperature profile are reviewed and discussed. The aftermath revealed that skin friction and suction effects are elevated along the magnetic field. The rate of heat transmission is enhanced by improving the value of the suction parameter. Magnetic field, Eckert number and suction boosted entropy over the shrinking plate.
