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

In the discussed paper, the damping parameter $E3$ and the radiation parameter $Rn$ are defined as follows (Eq. (32) in Ref. [1]):
$E3=d3d′μ˙λ3$
(1)

$Rn=16σ*T033kK⌢μ˙cp$
(2)

where $d$ is the channel half-width, $d′$ is the coefficient of viscous damping, $μ˙$ is the fluid dynamic viscosity, $λ$ is the wavelength, $σ*$ is the Stefan–Boltzmann coefficient, $T0$ is a reference temperature, $k$ is the absorption coefficient, $K⌢$ is the fluid thermal conductivity, and $cp$ is the specific heat.

The coefficient of viscous damping $d′$ is included in the following equation (Eq. (21) in Ref. [1]):
$[−...$
