THE DYNAMIC RESPONSE OF HELICOID ANEMOMETERS

The results of an analytical and experimental investigation of the dynamic response of a helicoid anemometer are presented. The experimental investigation was conducted using the NBS Unsteady Flow Facility and data are presented which illustrate the dynamic behavior in a spatially uniform, fluctuating flow with varying amplitudes, frequencies, and mean velocities. An analytical model governing the dynamic response is also presented and compared with the experimental results.
