A simple device for dynamic testing of X-configuration hot-wire anemometer probes

Abstract
An apparatus is described which was used to test dynamically the response of X-configuration hot-wire anemometer probes to enable a comparison with conventional static calibration to be made. It was found that the static calibration gave acceptable accuracy and that this accuracy was maintained to surprisingly high levels of the velocity fluctuation. The usefulness of such a device for directly testing a measurement system involving hot-wire anemometry is indicated.
