An Alternative Approach to Low-Speed in-situ Calibration of Hot-Wire Anemometers
Abstract
A hot-wire anemometer consists of a very thin wire with approximately 0.01mm diameter or less which is fixed between two probes. The working principle of the hot-wire anemometry is simply based on the relation between the heat loss from the thin cylinder wire due to the flow around the wire and the electric power supplied to keep the temperature of this wire constant.
