What I can say is that the information in the paper is inconsistent to say the least. For example,

The inlet diameter, D = 2 mm, according to the description in the 2nd paragraph in "Numerical Setup". So the inlet velocity can be calculated as:

Density = 0.851 kg/m^3

A = 3.14 e-6 m^2

v_inlet = 1.8551e-5 / (0.851 * 3.14e-6) = 6.95 m/s

The paper has both velocity contour plot and axial profile plot. The inlet velocity can be estimated from the plots to be about 1 m/s, that is very different from 6.95 m/s.
