Notes:
Direct measurement of the transfer function of hot-wire anemometers is needed whenever any turbulence frequencies approach the hot-wire frequency response. In particular, in high-speed applications it is not possible to obtain hot-wire frequency response sufficient to capture all of the turbulent kinetic energy. With knowledge of the hot-wire response, either an estimate of the turbulent integral scale or an approximation of the high-frequency part of the turbulent spectrum may be sufficient to correct measurements by post-detection frequency compensation. Described in this article are simple electronic circuits and a technique for obtaining sine-wave test frequency response of a hot-wire anemometer in a very short time without prohibitively high sampling rates.
