- The wake mode is characterized instead by a large-scale vortex shedding with a Strouhal number independent of Mach number.
- Comparison of their data with data in the figure suggests that the cylindrical enclosure between the two orifices raises the Strouhal number.
- Note the nearly pure tone at 2000 Hz with a Strouhal number of 0.21 protruding above the turbulent sound spectrum.
- The Strouhal number was essentially constant over the limited speed range, suggesting hole tone operation with Class I or Class II feedback.
- The dependence of Strouhal number on Reynolds number for this confined geometry is slightly negative as was found also for the Aeolian tone.
- Unlike the pipe organ, however, these instruments have side ports to change the resonance frequency and thus the acoustical Strouhal number.
- In this case, the equation could have been reformatted in terms of the acoustical Strouhal number as shown in the second equation above.
- For spheres in uniform flow in the Reynolds number range of 8x10 2 5 there co-exist two values of the Strouhal number.
- The slight discrepancy in level and frequency overlap suggests that both the dimensionless force and the Strouhal number had weak dependence on the Reynolds number.

- Kim found a similar result; the Strouhal number increased with Reynolds number and then stayed constant as shown in the lower figure on the right.
- For large Strouhal numbers ( order of 1 ), viscosity dominates fluid flow, resulting in a collective oscillating movement of the fluid " plug ".
- Both the Deltameter and hole tone data show the Strouhal number is a weak negative function of Reynolds number, which is squared in the sound power equation.
- 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.
- Since the jet slowed as it proceeded toward the hole, the speed of the vortex slowed with it so the frequency and Strouhal number was greater at closer spacing.

- For low Strouhal numbers ( order of 10 " 4 and below ), the high-speed, quasi steady state portion of the movement dominates the oscillation.
- The Strouhal number relates the frequency of shedding to the velocity of the flow and a characteristic dimension of the body ( diameter in the case of a cylinder ).
