Abstract

At high Reynolds numbers, a number of elongated intense vortex structures are observed to distribute randomly in space, which has been reported in recent computer simulations [1, 2] and experiments [3] of turbulence. These are called the worm structures. Each worm is found to be the Burgers vortex under local straining [2] and to be responsible for the signal usually referred to as intermittency [3]. Bearing these in mind, statistical properties of a model field associated with a random distribution of the isolated Burgers vortices are investigated and found to be in good agreement with those obtained in the real turbulence field [4].
