Vibration-induced boundary-layer destabilization achieves

01-05-2020· Thermal turbulence is well known as a potent means to convey heat across space by a moving fluid. The existence of the boundary layers near the plates, however, bottlenecks its heat-exchange capability. Here, we conceptualize a mechanism of thermal vibrational turbulence that breaks through the boundary-layer limitation and achieves massive heat-transport enhancement.

The detection of this presumed vibration-induced neuropathy and its distinction from compression neuropathies involving a localized primary lesion, such as carpal tunnel syndrome, thus requires a detailed investigation of nerve conduction within the hands.

Vortex-induced vibration Wikipedia

In fluid dynamics, vortex-induced vibrations (VIV) are motions induced on bodies interacting with an external fluid flow, produced by or the motion producing periodical irregularities on this flow.. A classical example is the VIV of an underwater cylinder. You can see how this happens by putting a cylinder into the water (a swimming-pool or even a bucket) and moving it through the

Vibration Wikipedia

Vibration is a mechanical phenomenon whereby oscillations occur about an equilibrium point.The word comes from Latin vibrationem ("shaking, brandishing"). The oscillations may be periodic, such as the motion of a pendulum—or random, such as the movement of a tire on a gravel road.. Vibration can be desirable: for example, the motion of a tuning fork, the reed in a woodwind instrument or

Improved long‐span bridge modeling using data‐driven

As the wind‐induced vibrations are not modeled within the identification algorithm, it is primarily suitable for acceleration records associated with wind speed below 5 m s −1. At present, the identification algorithm requires a low traffic density, as two vehicles crossing the bridge simultaneously or in a short time lead to two mixed‐signal clusters that are not easily separated.
