On Cup Anemometer Rotor Aerodynamics
The influence of anemometer rotor shape parameters, such as the cups' front area or their center rotation radius on the anemometer's performance was analyzed. This analysis was based on calibrations performed on two different anemometers (one based on magnet system output signal, and the other one based on an opto-electronic system output signal), tested with 21 different rotors. The results we...

متن کاملMultimode fibre laser Doppler anemometer with
The advantageous employment of multimode fibres for beam delivery in laser Doppler anemometers (LDA) is presented. Multimode fibres allow the transfer of significantly higher power into the LDA measurement volume and need lower alignment effort compared to the usually employed singlemode fibres. Powerful laser diodes can now be applied for LDA set-ups, enabling sensitive velocity measurements o...

15 صفحه اولA mm-Scale Aeroelastic Oscillation-Based Anemometer
By combining the aeroelastic and vortex-forced flutter modes of a thin plastic strip, its oscillation frequency can be confined to scale monotonically with fluid velocity. This principle has been used to produce a low-cost, mm-scale anemometer that measures air speed to ±(5% + 0.5m/s) from 118m/s. The device uses a 2mm slot-type photointerrupt detector to monitor the fundamental frequency of a ...
