Abstract

Some errors exist in the above paper.

1 1st error

From Eq. (4) in [1] it is found that the units of ${d_c}$ are $mse{c^{ - 2}}$ whereas the units of the same parameter in Eq. (9) in [1] and in Nomenclature are $m(length)$.

2 2nd error

The Eq. (13) in [1] is as follows

$${T_f}=0.0102\rho r{d_c}$$

(1)

where ${T_f}$ is the kinetic energy of the fluid (Nomenclature). From Eq. (1) it is found that the units of ${T_f}$ are $Kg{m^{ - 1}}$. However kinetic energy with these units does not exist in Physics.

3 3rd error

In Eqs. (1) and (4) in [1] the parameter t represents time and in Eq. (12) in [1] and in Nomenclature t is thickness (length).

4 4th error

In Eq. (1) in [1] the units of the term $2\xi \frac{{\partial w}}{{\partial t}}$ are $m{\sec ^{ - 1}}$ instead of $kg{m^{ - 1}}se{c^{ - 2}}$.

5 5th error

In figures appears an unknown dimensionless parameter dr.
