Analysis of periodic magnetohydrodynamics effects on triple diffusive nonlinear mixed convective flow of Eyring–Powell nanoliquid

Abstract

AbstractThe article spotlights aspects of the triply diffusive mixed convective flow of Eyring–Powell nanoliquid over a vertical plate. A periodic magnetic field with nonlinear convection is exhibited. The governing partial differential equations (PDEs) with boundary restrictions are the case paradigm transformed into a non‐dimensional system by feasible non‐similar transformations. The quasilinearization technique combined with an implicit finite difference scheme is used for numerical simulation, resulting in a block‐tridiagonal matrix form. Furthermore, a system of algebraic linear equations has been solved through Varga's algorithm. The numerical outcomes are correlated with various physical parameters graphically. The variations in the nonlinear mixed convection parameter and Powell–Eyring liquid parameter raise the skin friction coefficient more than a Newtonian fluid. In a periodic magnetic field, the fluid temperature rises and drops in the corresponding energy transfer rate. Also, wavy variations have been observed because of oscillatory magnetic fields. The current study can find its potential applications in medical, engineering and industrial developments, including polymer sheet manufacture, medicine cover coating, fibre production, crystal growth, heat exchangers and metal extrusion.
