| 11. | Two scaling laws were used; the Strouhal number was graphed as a function of Reynolds number.
|
| 12. | This selection of characteristic length can be used to present a distinction between Strouhal number and Reduced Frequency.
|
| 13. | Strouhal number in comparison with the second version which may be referred to as the " acoustical"
|
| 14. | The acoustical Strouhal number is essentially the "'Helmholtz number "'with the 2 deleted.
|
| 15. | Close examination of the data in the figure showed a slight negative dependence of Strouhal number on Reynolds number.
|
| 16. | A semi-empirical equation for the frequency, developed by Curle, when converted to Strouhal number, is
|
| 17. | The second figure on the right shows results from one study indicating a constant Strouhal number with Reynolds number.
|
| 18. | The higher frequency Strouhal number is caused by small-scale instabilities from the separation of the shear layer.
|
| 19. | A somewhat similar parameter is the Strouhal number, in form equal to the reciprocal of the Keulegan Carpenter number.
|
| 20. | At low Reynolds numbers the Strouhal number rises as inertial effects begin to dominate and then decays slightly at higher numbers.
