1. They noted that the Strouhal number remained constant with increase of speed. 2. This relationship expressed in terms of Strouhal numbers is: 3. At higher speeds the Strouhal number is close to that for the Aeolian tone. 4. Strouhal number and the " acoustical"5. A review of the literature produced the figure on the right for the Strouhal number . 6. The Strouhal number data showed clearly the almost linear relation between frequency and initial jet speed. 7. The second equation suggests that the Strouhal number is a weak negative function of Reynolds number. 8. Poblete et al ., found Strouhal numbers between 0.12 and 0.18. 9. Oscillation at intermediate Strouhal numbers is characterized by the buildup and rapidly subsequent shedding of vortices. 10. Now the Strouhal number can be derived directly from the dimensionless form of the mass continuity equation.
