Equilibrium of flowing plasma in tokamak in the frame of Hallmagnetohydrodynamics

V I Ilgisonis2001年Plasma Physics and Controlled FusionIF 2.2出版社

The stationary toroidal rotation of a plasma in an axisymmetricmagnetic field is studied both analytically and numericallyin the frame of Hall magnetohydrodynamics (HMHD).The HMHD analogue of the Grad-Shafranov equation is derived foran axisymmetric magnetic confinement configuration (like atokamak) in the form admitting the simple transition tothe limit of one-fluid magnetohydrodynamics (MHD). It is shown thatHMHD restricts the freedom of stationary plasma parameters more thanone-fluid MHD. The stationary solutions of the certain class areoptimized to reach higher values of the ratio β of theplasma pressure to the magnetic field pressure.

軸対称磁場中のプラズマの定常トロイダル回転を、ホール磁気流体力学(HMHD)の枠組みで解析的および数値的に研究する。軸対称磁気閉じ込め配位(トカマクなど)に対して、単流体磁気流体力学(MHD)の極限への簡単な遷移を許容する形式で、HMHD版のGrad-Shafranov方程式を導出する。HMHDは、単流体MHDよりも定常プラズマパラメータの自由度を制限することが示される。特定のクラスの定常解は、プラズマ圧力と磁場圧力の比βのより高い値を達成するように最適化される。
