There are some errors in Ref. [1] paper.

Equation (13) in Ref. [1] is as follows:
(1)
Equation (18) in Ref. [1] is as follows:
(2)

In a physics equation, all terms must have the same units, and from Eq. (1) it is found that the units of stream function ψ are m2s−1⁠, and from Eq. (2) it is found that the units of X(x),Y(y) are also m2s−1⁠.

Equation (34) in Ref. [1] is as follows:
(3)

where the symbol...
