3-COMPONENT VELOCITY-MEASUREMENTS IN TURBULENT FLOWS USING A TECHNIQUE OF ROTATING PROBE WITH AN INCLINED HOT-WIRE

A technique has been developed to measure three components of mean vel ocity, six components of the Reynolds stress, ten components of the tr iple correlation, and fifteen components of the quadruple correlation of fluctuating velocity in steady turbulent flow using Hot-Wire Anemom etry (HWA). The hot-wire signal was acquired by rotating a single incl ined hot-wire probe toward a number of spatial orientations at the sam e location in a turbulent flow-held. Velocity information has been com puted by decomposing the response equation for the effective velocity of the hot-wire probe.
