| Summary: | Fluid motions in cylindrical domains have many applications in vital areas like as chemical processes, food industry, bioengineering, oil exploitation, etc. This study investigates the boundary layer flow of an electrically conducting Jeffrey fluid over a stretching cylinder. The energy equation accounts for viscous dissipation and Joule heating, while the mass transfer equation incorporates chemical reaction effects. The present analysis also focuses on the partial slip assumption, which gives rise to a nonlinear Robin-type (mixed) boundary condition in axial velocity. A mathematical model is developed using partial differential equations, which are converted into dimensionless ODEs via similarity transformations. These expressions are then solved numerically with the aid of the bvp4c solver. Graphical representations are utilized to examine the effects of key factors on the velocity and temperature profiles, as well as on the skin friction coefficient and the local Nusselt number. An important finding of the analysis is that the reduction in axial flow, which is caused by an increase in either relaxation time or partial slip boundary or magnetic field strength, implies a deceleration in radial flow, which eventually weakens the established flow and thermal boundary layer is, therefore, enhanced. On the other hand, an appreciable decline in driving force on the cylindrical surface is noticed whenever either the slip coefficient or the retardation time enlarges. |
