What is it about?
Recent advances in flow visualization techniques have provided a fascinating insight into the complex dynamics of coherent flow structures. In turbulent pipe flow, coherent organizational states are suspected to form the skeleton of the turbulent dynamics, around which the chaotic dynamics are organized. In this work, by means of stereoscopic particle image velocimetry and conditional averaging techniques, we are able to detect and visualize these coherent organizational states at moderate turbulence.

Why is it important?
The experimental results uncover turbulent dynamics so far unexplored by providing a unique insight into turbulent pipe flow regarding its phenomenology and statistical features which are highly relevant to better understand, predict, and model turbulence.
