Numerical analysis of Darcy resistant Sutterby nanofluid flow with effect of radiation and chemical reaction over stretching cylinder: induced magnetic field

Abstract

<abstract> <p>In this analysis, Sutterby nanofluid flow with an induced magnetic field at a nonlinear stretching cylinder is deliberated. The effects of variable thermal conductivity, Darcy resistance, and viscous dissipation are discussed. Thermal radiation and chemical reaction are considered to analyze the impact on the nonlinear stretching cylinder. The governing model of the flow problem is developed under the boundary layer approximation in terms of partial differential equations. Partial differential equations are transformed into ordinary differential equations by performing the suitable transformations. A numerical structure is applied to explain ordinary differential equations. The impact of each governing physical parameters on the temperature, concentration, skin friction, Sherwood, and Nusselt number is presented in graphs and tabular form. Increment in Prandtl number, which declined the curves of the temperature function. Temperature declined because the Prandtl number declined the thermal thickness as well as reduce the temperature of the fluid. Temperature curves showed improvement as Eckert number values increased because the Eckert number is a ratio of kinetic energy to the specific enthalpy difference between the wall and the fluid. As a result, increasing the Eckert number causes the transformation of kinetic energy into internal energy via work done against viscous fluid stresses.</p> </abstract>

“…These enhanced characteristics make the hybrid nanofluids more functional in comparison to nanoliquids. The most recent studies in the field of nano, hybrid, and ternary nanofluids have been reported by different researchers around the globe. − Scientists have made efforts to explore the functioning of hybrid nanofluids under physically established conditions. In the presence of a transverse magnetic field, Ganesh et al studied the steady laminar flow of a fluid between two permeable parallel plates.…”

“…The research indicated amplification in the microorganism population associated with higher Peclet numbers. Nadeem et al 24 presented a numerical assessment of Sutterby nanoliquid flow through a pipe, demonstrating an increase in fluid hotness in the presence of greater Eckert numbers. Asfour and Ibrahim 25 employed magneto Sutterby nano liquid, incorporating a modified version of Darcy's law, and utilized a combination of dual-step difference transparent and finite approach to obtain solutions.…”
