Convective and viscous fluxes in strongly rotating tokamak plasmas

W.M. Stacey Jr.1990年被引用 3Nuclear FusionIF 3出版社

A formalism is presented for interpreting convective and viscous energy fluxes derived from experimental data and for correcting for them in the interpretation of measurements of the conductive heat flux. The corrections are shown to be significant in two JET pulses, suggesting that they should be taken into account in the experimental determination of thermal diffusivity in strongly rotating tokamak plasmas. A supplementary theory for ion and impurity particle fluxes, which retains ambipolarity in the presence of large anomalous electron fluxes, is presented. A theory, based upon gyroviscosity (the basis for which remains controversial), for the radial flux of toroidal momentum is presented and is shown to be in reasonable agreement with experiment for two JET pulses.

実験データから得られた対流および粘性エネルギー束を解釈し、伝導熱流束の測定の解釈においてそれらを補正するための定式化を提示する。この補正は2つのJETパルスにおいて有意であることが示され、強く回転するトカマクプラズマにおける熱拡散率の実験的決定において考慮されるべきであることを示唆している。大きな異常電子束の存在下で両極性を保持する、イオンおよび不純物粒子束に関する補足的な理論を提示する。ジャイロ粘性(その基礎は依然として議論の余地がある)に基づく、トロイダル運動量の径方向束に関する理論を提示し、それが2つのJETパルスについて実験と妥当な一致を示すことを示す。
