Contribution of coherent structures in drift-wave turbulence to particle transport

摘要

The nonlinear dynamics and transport properties of drift-wave turbulence in the two-dimensional reduction are considerd. The drift-wave turbulence consists of monopolar coherent structures. The monolopar structures are tracked in time. Averaging over a great number of events, it is found, that the structures account for convective particle transport additional to the fluctuation induced transport.
