Analysis of the velocity, thermal, and concentration MHD slip flow over a nonlinear stretching cylinder in the presence of outer velocity

Abstract

The intention of the present work is to analyze the influence of magnetohydrodynamic slip flow with radiation effect toward a nonlinear stretching cylinder in the presence of outer velocity. Similarity variables are applied to convert the governing partial differential equations into ordinary differential equations. The Runge‐Kutta‐Fehlberg approach was adopted to numerically solve the modified equations by use of the Shooting method. The effect of prominent fluid parameters especially the velocity slip parameter, temperature slip parameter, concentration slip parameter, outer velocity, magnetic parameter, nonlinear stretching parameter, Schmidt number, and Eckert number on the velocity, temperature, and concentration have been examined and are displayed through graphs and tables. Numerical results of various parameters involved for the skin friction coefficient, the local Nusselt numbers, and the local Sherwood numbers are determined and also discussed in detail. In the present study, we used MATLAB for finding the final outcomes and relating the conclusive results for −θ0′(0) with those of already published papers. The outcomes reveal that with an increase in outer velocity, the fluid velocity increases while the temperature and concentration decrease. In the case of a higher nonlinear stretching parameter, the temperature as well as concentration decrease. The findings of the present study help to control the rate of heat transportation and highlight many applications in the insulation of wires, manufacturing of tetrapacks, production of glass fibers, fabrication of various polymers and plastic packs, rubber sheets, and so forth, where the quality of the desired product depends on the rate stretching, external magnetic field, and the composition of the material used, and manufacturing processes.

“…Goyal et al [9] examined the GFEM examination in MHD nanofluid flow towards extending sheet and the FEM approach was implemented to solve system. Vinita et al [10] explained the effect of variable slip flows in addition to thermal radiation in MHD nanofluids induced by non linear stretched surface. Vinita et al [11] examined radiation effect on MHD free stream velocity nanofluid flow induced by stretchable cylinder in presence of chemically reactive species by applying RKF technique using ODE45 solver in MATLAB.…”
