A numerical analysis of reversed field pinch equilibrium with energy transport and dynamo electric field

S.C. Guo, C.L. Surdo, R. Paccagnella1997年被引用 2Nuclear FusionIF 3出版社

Reversed field pinch equilibria have been numerically studied on the basis of a set of stationary dissipative MHD equations, where mass, momentum and energy conservation, Ohm's law and perpendicular heat transport are included. Moreover, an effective dynamo electric field epsilon is taken into account. The equilibrium magnetic field B, plasma temperature T and pressure p, as well as some associated fields are determined consistently by this system. Two types of dynamo model epsilon = alpha .B, with alpha either a scalar (isotropic- alpha model) or a tensor (symmetric hyperbolic tensor- alpha model), have been used and are discussed. The results are found to be in good agreement with the experimental measurements

逆転磁場ピンチ平衡は、質量、運動量、エネルギーの保存則、オームの法則、および垂直方向の熱輸送を含む一連の定常散逸MHD方程式に基づいて数値的に研究された。さらに、有効なダイナモ電場εが考慮された。平衡磁場B、プラズマ温度T、圧力p、および関連する諸量は、この方程式系によって自己無撞着に決定された。αがスカラーである場合(等方性αモデル)とテンソルである場合(対称双曲型テンソルαモデル)の2種類のダイナモモデルε = α・Bが用いられ、考察された。その結果は実験測定値と良好な一致を示すことが見出された。
