| 内容記述 | The gyro-fluid model proposed by Ottaviani et. al is extended, in which the ion parallel flow and ion neoclassical viscosity are taken into account. Using this model, the ion temperature gradient driven drift wave turbulence is analyzed. The saturation level and ion heat flux are evaluated in case with profile relaxation. The multi-scale interaction between the micro-scale and meso-scale is observed in our simulations. The avalanche process and turbulence spreading occur in the nonlinear phase. In addition, the various kind of parallel scheme are tested to improve the performance of the code. We find a way which gives better parallel efficiency of the spectral code. |
