The following corrections are to be noted with reference to the original paper by Narayana et al. [ASME J. Heat Transfer, 2013, 135(3), p. 032501].

The equation governing momentum transfer in page 2, Eq. (3) should be replaced with
$∂∂y(μρ∞K*un)+∂∂y(bK1/n+1u2)=g(β∂T∂y+β*∂C∂y)$
(3)

This is due to the fact that in the original paper while modeling the quadratic drag term in the case of natural convection from a vertical plate in a thermally stratified porous medium involving power-law liquid, the authors have inadvertently missed the permeability factor $K-(1/n+1)$.

This change in the equation of...
