الملخص
The author [1] studied the effects of thermal radiation , variable viscosity and
heat generation on the on boundary layer flow and heat transfer over an
exponentially stretching porous sheet with constant heat flux .
The physical quantities of interest in the boundary layer flow and heat transfer
studies are the local skin-friction coefficient and the surface heat flux.
Unfortunately, there are fundamental errors in the definitions of these
quantities in the above paper [1] :
