Proper orthogonal decomposition was originally introduced in turbulence to identify large-scale pat- terns in turbulent flows. Over the years, several extensions have been formulated in order to strengthen its model-predictive abilities, with limited success in the case of fully developed turbulence. The physics-based insight obtained from the proper orthogonal decomposition structures and othBer turbulence analysis techniques could lead to significant developments in that respect. Experimental and numerical results will be presented to illustrate these conjectures.
