Cho and Mote found that the Strouhal number was between 0.1 and 0.2 where h was the blade thickness.

Close examination of the data in the figure showed a slight negative dependence of Strouhal number on Reynolds number.

Comparison of their data with data in the figure suggests that the cylindrical enclosure between the two orifices raises the Strouhal number.

Cylinder vortex development It is surprising how often oscillatory flow phenomenon have Strouhal Numbers in this range.

For low Strouhal numbers (order of 10 −4 and below), the high-speed, quasi steady state portion of the movement dominates the oscillation.

If the Strouhal number were graphed in lieu of the frequency, it would have shown that contours were reasonably constant similar to those for the hole tone.
