Anomalous Transport in Two-Dimensional Plasma Turbulence
Conference paper
Abstract
Transport properties of passive particles evolving in two dimensional flows are investigated. Flows governed by point vortices and by the Charney-Hasegawa-Mima equation are considered. Transport is found to be anomalous with a non linear evolution of the second moments with time and for all considered cases the characteristic exponent is found to be close to 1.75. The origin of this behavior is traced back to the existence of chaotic jets in these systems.
