Abstract

 The vortex shedding behind a cylinder in a fully developed pipe flow is investigated by applying new measurement and data-analysis techniques. An ultrasound anemometry technique, providing the multipoint information of the flow, is employed. The measured instantaneous velocity fluctuations are decomposed by the empirical eigenfunctional analysis known as the proper orthogonal decomposition. The predominant modes of fluid motions are well identified by this technique, and their time–frequency features are discussed.
