Abstract
The present comment concerns some doubtful results included in the above paper.
Highlights
Where K is the porous medium permeability, U0 is a reference velocity, and υ is the fluid kinematic viscosity
For the above dimensionless momentum equation (2) to be correct, the magnetic parameter must be defined as all calculation and results by Sahoo [1] are based on the wrong definition of M ((8) of the present work)
Comparing the cases Gr = 2, Gm = 2.5, Sc = 2, and Gr = 2, Gm = 2, Sc = 2, it is seen that the greater mass Grashof number Gm corresponds to greater velocity; that is, as the mass Grashof number increases the velocity increases too
Summary
Where K is the porous medium permeability, U0 is a reference velocity, and υ is the fluid kinematic viscosity. In the paper [1], the momentum equation (2) includes the term (K0/ρ)(∂3u/∂t∂y + V0(∂3u/∂y3)). The transformed dimensionless momentum equation is as follows ((5) in [1]):
