RESUMO

This paper is concerned with studying the effects of thermal radiation on heat and mass transfer of a non-Newtonian Jeffrey nanofluid over an extrusion stretching sheet in the presence of nonuniform heat source/sink and suction. The highly nonlinear governing partial differential Jeffrey fluid equations are transformed into coupled nonlinear ordinary differential equations using similarity transformations and then solved numerically using the Runge-Kutta-Fehlberg method. The effects of various physical parameters on the velocity, temperature, and concentration fields, as well as on the skin-friction coefficient, local Nusselt, and Sherwood numbers are illustrated graphically to show some important physical phenomena. It is observed that the velocity, temperature, and concentration profiles increase with increasing the thermal radiation parameter.
