Long-range distributed optical fiber hot-wire anemometer based on chirped-pulse ΦOTDR.
Optics Express, 2018 We demonstrate a technique allowing to develop a fully distributed optical fiber hot-wire anemometer capable of reaching a wind speed uncertainty of ≈ ±0.15m/s (±0.54km/h) at only 60 mW/m of dissipated power in the sensing fiber, and within only four ...

High-sensitivity hot-wire anemometer using cobalt-doped fiber-based long-period gratings.
Optics ExpressA high-sensitivity hot-wire anemometer is proposed for use with a cobalt-doped fiber (CDF) based long-period grating (LPG) heated optically by a 1480 nm laser.

Wind Energy and the Turbulent Nature of the Atmospheric Boundary Layer [PDF]
, 2012 Wind turbines operate in the atmospheric boundary layer, where they are exposed to the turbulent atmospheric flows. As the response time of wind turbine is typically in the range of seconds, they are affected by the small scale intermittent properties of

Excitation of localized wave packet in swept-wing supersonic boundary layer
MATEC Web of Conferences, 2017 The evolution of the artificial wave packet in swept-wing supersonic boundary layer was experimentally studied at M = 2. The localized disturbances were generated by a pulse glow discharge. Measurements were provided by a hot-wire anemometer. The spatial
