| Research Abstract |
The object of this study is to understand formation mechanisms of turbulence meso-scale structures, which play important roles on transport phenomena in torus magnetized plasmas. Simulations of resistive drift wave turbulence in cylindrical plasmas clarified the elementary processes of saturation and selection of the turbulent structures. By developing a simulation code for drift-interchange instability in helical plasmas and carrying out numerical diagnostics with finite resolutions on the simulation data, the feature and formation mechanism of turbulent structures were shown, and the basic framework for efficient collaboration between simulations and experiments has been constructed.
