The present discussion concerns some doubtful results included in the above paper.

In the above paper, the momentum, energy equation, and the concentration of the chemical species A and B equations are as follows (Eqs. (4)–(7) in Ref. [1]):
$u∂u∂x+v∂u∂y=υ∂2u∂y2+ue∂ue∂x+λue2∂2ue∂x2−λ(u2∂2u∂x2+v2∂2u∂y2+2uv∂2u∂x∂y)$
(1)

$u∂T∂x+v∂T∂y=α(∂2T∂x2+∂2T∂y2)+(−Δ...$
