Abstract
In the above paper the author studied the effects of the thermal conductivity parameter, suction parameter, dimensionless Powell–Eyring parameters and the Prandtl number on the flow and heat transfer as well as on the local skinfriction coefficient and the local Nusselt number of Powell–Eyring fluid over an exponentially stretching porous sheet with heat flux . There are many fundamental errors:
