Validation
The Strouhal Number (St) is calculated as follows:
|
11.1 |
where,
| f | Frequency of the Lift force, which is the sum of pressure and shear forces in the y-direction on the cylinder = 0.16393 |
| D | Diameter of the cylinder (m) = 1 |
| U | Velocity (m/s) = 1 |
The comparison of the strouhal number from experiments and Simerics-MP+ are as follows:
| Experiment | Simerics MP+ | |
|---|---|---|
| Strouhal Number | 0.164 | 0.164 |
