    "abstract": "The streamwise and transverse velocities are measured simultaneously in\nisotropic grid turbulence at relatively high Reynolds numbers, Re(lambda) =\n110-330. Using a conditional averaging technique, we extract typical\nintermittency patterns, which are consistent with velocity profiles of a model\nfor a vortex tube, i.e., Burgers vortex. The radii of the vortex tubes are\nseveral of the Kolmogorov length regardless of the Reynolds number. Using the\ndistribution of an interval between successive enhancements of a small-scale\nvelocity increment, we study the spatial distribution of vortex tubes. The\nvortex tubes tend to cluster together. This tendency is increasingly\nsignificant with the Reynolds number. Using statistics of velocity increments,\nwe also study the energetical importance of vortex tubes as a function of the\nscale. The vortex tubes are important over the background flow at small scales\nespecially below the Taylor microscale. At a fixed scale, the importance is\nincreasingly significant with the Reynolds number.",
