| 1. | Wake turbulence exists in the vortex flow behind the wing.
|
| 2. | This classic fluid mechanics result is " irrotational vortex flow ."
|
| 3. | Tornadoes and dust devils display localised vortex flow.
|
| 4. | In his thesis he developed a perturbation mathematical method to predict secondary vortex flows in polymeric fluids.
|
| 5. | Their work indicated symmetric unstable vortex flow as would be expected but there was no mention of stages.
|
| 6. | Any fluid, including water in a stream, can only flow around a bend in vortex flow.
|
| 7. | If the two cylinders rotate in opposite sense then "'spiral vortex flow "'arises.
|
| 8. | As with all vortex flow, the speed of the flow is fastest at the core of the vortex.
|
| 9. | Early on individual sessions at scientific conferences were devoted to vortices, vortex motion, vortex dynamics and vortex flows.
|
| 10. | And heating of different surfaces; upwind wall, downwind wall, canyon floor, changes the vortex flow in different manners.
