Popis:	A new directionally sensitive velocity measurement system based upon a single oscillating hot-wire probe has been developed. The vibration of the hot-wire was effected by a piezoelectric oscillator that could be driven at different amplitudes and frequencies. The sign of the local flow velocity was determined by the phase shift between the motion and the output from the hot-wire. The system was used to measure mean and fluctuating velocities profiles of the separated flow behind a backward facing step.
