The 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.
“…Also, Heckel et al, 4 Datta et al, 5 Singh et al, 6 Singh and Roy, 7 and so on have worked on combined convection flow over a vertical slender cylinder. However, Patil et al 30,36,37 are the only researchers who worked on surface roughness impacts on the boundary layer characteristics. In the earlier studies, the flow over a slender cylinder analysis was confined to only forced convection flow.…”
The present work explores the analysis of magnetohydrodynamics nonlinear mixed conv ective nanofluid flow over a vertical slender cylinder in the presence of surface roughness. The application of the present study can be found in the process of coating wires. In fact, during such a process, thin wires in the slender cylinder need to be cooled, and also heat and mass transfer rates need to be controlled through nanofluid and liquid hydrogen to yield better results. By employing nonsimilar transformations, the partial differential equations governing the flow problem are reduced to dimensionless equations. Furthermore, the Quasilinearization technique and implicit finite difference scheme are used to solve the dimensionless governing equations. The novelty of the analysis is the impacts of surface roughness, diffusion of liquid hydrogen, and the presence of nonlinear mixed convective flow over a slender cylinder. The numerical results reveal that the energy transport strength and surface drag coefficient enhance with the roughness parameter values. The nanoparticle volume fraction profile reduces, while nanoparticle Sherwood number enhances with increasing values of velocity ratio parameter. The presence of nanoparticles in the conventional fluid diminishes the energy transfer value significantly for both smooth and rough surfaces. The velocity of the
