旨在研究和验证TOKAMAK等离子体转动机理,精心挑选了具有代表性的标准新经典及其推广的等离子体转动理论模型,编制出计算程序ROTATE CODE。采取新的抛物线分布函数双指数调节的参数拟合公式,结合HL-1M的实验测量数据,进行理论模拟计算和比较研究。在HL-1M常规运行参数下,计算结果直观地预言主离子与杂质离子的环向转动速度和极向转动速度的径向分布,在边缘区与Mach探针的实验测量结果合理地相符。这些工作为设计光谱测量仪器精度提供理论依据,对实验方案的制定和测量数据的分析有参考和启发作用。
The purpose of this paper is to study and validate the TOKAMAK plasma rotation mechanism, carefully select the representative standard new classical and its extended theoretical model of plasma rotation, and develop the calculation program ROTATE CODE. A new parametric fitting formula of double exponential function of parabolic distribution function is adopted, combined with the experimental data of HL-1M, theoretical simulation and comparative study are carried out. Under the conventional operating parameters of HL-1M, the calculated results intuitively predict the radial distribution of the toroidal rotation speed and the polar rotation speed of the main ions and impurity ions, which are reasonably consistent with the experimental results of the Mach probe in the edge region. These works provide a theoretical basis for the design of the accuracy of spectrometric instruments and have reference and inspiration for the formulation of experimental schemes and the analysis of measurement data.
