Stagnation point flow of Jeffrey nanofluid with activation energy and convective heat and mass conditions

Abstract

This research reports stagnation flow of Jeffrey nanofluid toward a permeable stretching cylinder. Brownian motion, thermophoresis, thermal radiation and viscous dissipation are explored. Convective heat-mass conditions are implemented. Moreover, activation energy is taken into account. Transformations (variables) are utilized in order to convert PDEs (Partial DIfferential Equations). (continuity, momentum, energy and concentration equation) into ODEs (Ordinary Differential Equations). Resulting systems are solved by the optimal homotopy analysis method. Behaviors of involved flow, heat and mass transport parameters for velocity, concentration and temperature are examined. Surface friction and Sherwood number and Nusselt numbers are also examined. Velocity of the fluid can be minimized by higher estimations of parameter due to ratio of relaxation and retardation time, suction and injection parameters. Decay in fluid temperature is observed for higher Prandtl number and Deborah number for relaxation time parameter. Skin friction coefficient is controlled via higher values of parameter due to ratio of relaxation and retardation time. Intensification in heat transfer rate (Nusselt number) is seen via higher values of parameter due to ratio of relaxation and retardation time, radiation parameter, Prandtl number and Deborah number for relaxation time and curvature parameter.
