First the design, the characteristics, and the calibration of a very low-speed micro wind tunnel are described. Then the principle, operation and performance of three different anemometers at these low speeds are discussed. These instruments are: 1) the hot-spot anemometer, based on the measurement of the travelling time of a hot cloud, 2) the drag anemometer which consists of a small plate mounted to the moving coil mechanism of a micro ammeter, and 3) a constant temperature hot-wire anemometer. The comparison of the merits and disadvantages of these instruments shows that in most instances the hot-wire anemometer is superior to the two other anemometers.technical reportsengCopyright and other restrictions may apply.
