Abstract

Based on the need to investigate the accuracy of hot-wire anemometers in high Reynolds number turbulent boundary layers, we pursue a direct method for testing the dynamic response of a HWA system to very high frequency velocity fluctuations (up to 50 kHz). To achieve this we will use a fully-developed turbulent pipe-flow to provide the input velocity perturbations. Having established the accuracy of this method of testing, we will also seek to test the extent to which the amplitude and sign of velocity fluctuations close to the wall in a turbulent boundary layer influences the anemometer response.
