strouhal number in a sentence

Examples

1. 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.
2. For large Strouhal numbers ( order of 1 ), viscosity dominates fluid flow, resulting in a collective oscillating movement of the fluid " plug ".
3. 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.
4. 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.
5. 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.
6. Based on a Strouhal number of 0.20, the characteristic dimension " ? " was calculated to be near ?inch; the boundary layer thickness.
7. For low Strouhal numbers ( order of 10  " 4 and below ), the high-speed, quasi steady state portion of the movement dominates the oscillation.
8. 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 ).
9. Cho and Mote found that the Strouhal number St = " " was between 0.1 and 0.2 where " h " was the blade thickness.
10. In another study one set of their frequency data was recalculated in terms of Strouhal number and it was found to rise slowly and then be constant over a range of flow rates.
