Descrição: Visual evidence has been obtained for the existence in fully developed turbulence of characteristic small-scale flow patterns which are tentatively identified as layered vortex sheets. The pattern geometry is consistent with previously observed properties of intermittent bursts. The structures are found to scale with the turbulence scales and to exhibit a spatial variation limited by the Kolmogorov length. At microscale Reynolds numbers of order 100, this organized fine-scale structure occupies an appreciable fraction of the total fluid volume. (C.D.)
