Turbulence gets eagles up to speed
湍流 老鹰 速度
2021/6/14
Most sensible air travelers dread turbulence. A little atmospheric hiccup can shake airplanes, rattle nerves and spill beverages. A Cornell-led collaboration has found that birds don’t mind at all.
An aero-elastic flutter based electromagnetic energy harvester with wind speed augmenting funnel
aero-elastic flutter electromagnetic energy harvester wind speed augmenting funnel
2015/6/30
This paper investigates the efficiency of wind speed augmenting funnel incorporated with an aero-elastic-flutter based, energy harvester. Flutter phenomenon has been used to convert wind flow energy i...

Dual-camera system for high-speed imaging in particle image velocimetry
Dual-camera system high-speed imaging particle image velocimetry Fluid Dynamics
2012/3/31
Particle image velocimetry is an important technique in experimental fluid mechanics, for which it has been essential to use a specialized high-speed camera. However, the high speed is at the expense ...
Numerical investigation of rotor-stator interactions in a 1.5-stage low-speed axial compressor
axial compressor rotor-stator-interaction periodic unsteady blade pressure uctuation unsteady blade pressure force
2007/1/15
The relative motion of rotor and stator leads to viscous and inviscid interactions between the blade rows. This is the reason why the °ow in turbomachines is periodically unsteady. The unsteady °ow &m...
