Intensity-interrogated hot-wire anemometer based on chirp effect of a fiber Bragg grating.
An intensity-interrogated optical fiber hot-wire anemometer based on the chirp effect of fiber Bragg grating (FBG) is presented. The FBG is coated with a silver film and heated optically by a 1480 nm laser beam, which is coupled into the fiber cladding ...

Choosing a Universal Air Collector Design for a Cylindrical-Shaped Hot-Wire Anemometer
Air flow measurement at the outlets of air terminal devices installed in ventilation systems is very difficult. At the outlets of anemostats, swirl diffusers, grilles, the air flow can swirl, contract, or expand sharply, change its direction, etc ...

A Numerical-Experimental Assessment of the Dilute Phase and Erosion in a Larvae-Killing Processing System: Considering the Geometry Variation. [PDF]
The Reynolds stress (RSM) and Discrete phase models (DPM) were used to model the conveying of wheat in the dilute phase. The contours related to the velocity magnitude, static pressure, dynamic pressure, erosion, vorticity magnitude, and turbulence intensity were investigated in four different cross‐section ratios.
