- 論文の詳細を見る
The dynamics of the magnetic island affected by the microscopic turbulence is analyzed using the renormalized reduced MHD equations. The evolution equations of the island width w(t) and rotation frequency ω(t) are derived in the cold ion approximation. It is found that the effects of the current flowing in a layer close to the separatrix are important to evaluate the effects of turbulent diffusions on the island rotation. As the result, the rotation of the magnetic island is driven by anomalous resistivity, and suppressed by anomalous ion viscosity and thermal conductivity.
