Abstract
A method for low velocity calibration of hot-wire anemometers, in whic h the probe is mounted on a pendulum arm, is presented. The calibratio n constants are determined from recorded traces of the anemometer sign al obtained in the forward swing of the pendulum with the probe mounte d at two different radii along the arm. Typical calibration results ar e presented and the use of a modified King's law in the low Reynolds n umber range is discussed.
