Thermal radiation effect in MHD flow of powell - Eyring nanofluid induced by a stretching cylinder

In this paper, the steady magnetohydrodynamic (MHD) boundary layer flow of Powell - Eyring nanofluid over a stretching cylinder is discussed. Analysis is performed in the presence of thermal radiation. Variable temperature and concentration are assumed at the surface of cylinder. The arising governing equations of momentum, energy, and concentration are transformed into nonlinear ordinary differential equations by appropriate transformations. Convergent solutions of the governing equations are found. The behavior of pertinent parameters on the velocity, temperature, and concentration profiles are depicted graphically and analyzed comprehensively in detail. The presented results are also compared with the previous published work in the limiting sense.
