Abstract

The paper reviews the method of simultaneous flow velocity and temperature measurements using a single-wire probe operating in a constant-temperature anemometer (CTA) circuit where temperature is modulated sinusoidally. Acordingly, the hot wire supply circuit must allow for modulating the overheating ratio and hence the temperature of the hot wire.
