Abstract
We propose to improve a new experimental methodology of determining the amplitude-frequency characteristics of a system of hot-wire anemometry with the use of a short-pulse laser action on the hot-wire sensor. Mistakes of the previous study are taken into account. The amplitude-frequency characteristics of a constant-temperature anemometer with a wire sensor are obtained, and comparisons with the results obtained by a standard method of determining the amplitude-frequency characteristics are performed.
