| 1. | It can be employed to simulate the acoustic streaming phenomena.
|
| 2. | However, they are not the only driven forces for the acoustic streaming.
|
| 3. | The magnitude of acoustic streaming depends on the power and frequency of input.
|
| 4. | To get the acoustic streaming, the first-order equations should be solved first.
|
| 5. | For applications in a static flow, the fluid velocity comes from the acoustic streaming.
|
| 6. | Thus, the acoustic streaming should be smaller than the main flow for most continuous flow applications.
|
| 7. | As said, the acoustic streaming is driven by mass and force sources originating from the acoustic attenuation.
|
| 8. | The boundary vibration may also have contribution to the acoustic streaming, especially to boundary driven streaming .
|
| 9. | The estimated magnitude of acoustic streaming is in range of 1 �m / s ~ 1 mm / s.
|
| 10. | Figure 3 is one example of acoustic streaming around a solid circular pillar, which is calculated by FEM method.
