Evaluation of the dynamic characteristics of the K-Gill anemometer

Wei, Chunghwa 04 March 2009 (has links)
The dynamic characteristics of the K-Gill anemometer were evaluated by comparing the anemometer with a hot wire system in a field test, after the static characteristics of the anemometer had been evaluated in a wind tunnel test. The wind tunnel test showed a non-linear and a non-cosine behavior, as shown in previous studies (Ataktürk, 1988; Pond et al., 1979). The turbulence energy spectra from the field test revealed that the propeller anemometer behaves like a single-pole low-pass RC filter, as suggested in previous studies (Ataktürk, 1988; Pond et al., 1979; MacCready and Jex, 1964). The test results showed that mean wind velocity components can be measured with an error of 2%. To determine the Reynolds stress values, uw covariance and friction velocity from different methods were compared. When the stability conditions were unknown, the resulting Reynolds stress estimations have 15% relative differences between different methods. / Master of Science
