在完整的Bonoli-Englade模拟模型基础上,编制了一组即适合用于稳态,又适用于准稳态低混杂波电流驱动(LHCD)的模拟计算代码。它包括平衡计算,环形射线追踪和福克-普朗克计算。其中采用了Shafranov平衡位形和热等离子体波色散关系。福克-普朗克计算考虑了由Pitch角散射引起高垂直温度造成的二维效应,同时还考虑了相对论效应。代码能重复以往文献显示的结果。结合阵列天线计算代码,完成了真实低混杂波功率注入时LHCD的静态模拟(未包括场演化、输运过程),获得波传播、功率沉积、驱动电流和电流驱动效率等LHCD主要宏观、微观物理量。文中给出了与HL-1LHCD实验相关的计算结果。对AlcatorC和HL-1装置计算结果表明,模拟结果与实验结果一致。所得数值模拟结果有助于LHCD物理的理解和实验结果的分析。对于提高LHCD效率具有重要意义。
Based on the complete Bonoli-Englade simulation model, a set of simulation calculation codes suitable for steady-state and low quasi-steady-state low-noise hybrid current drive (LHCD) was developed. It includes balancing calculations, ring ray tracing and Falk-Planck calculations. Which uses Shafranov equilibrium shape and thermal plasma wave dispersion relationship. The Foucault-Planck calculation takes into account the two-dimensional effect caused by the high vertical temperature due to Pitch angle scattering and also takes into account the relativistic effect. The code can repeat the results of previous literature. Combined with the calculation code of the array antenna, the LHCD static simulation (excluding field evolution and transport process) during real low-noise hybrid power injection is completed, and the main macroscopic and microscopic physical quantities of LHCD such as wave propagation, power deposition, driving current and current driving efficiency are obtained . The calculation results related to the HL-1LHCD experiment are given in the paper. Calculations on AlcatorC and HL-1 devices show that the simulation results are consistent with the experimental results. The numerical simulation results are helpful for the understanding of LHCD physics and the analysis of experimental results. It is of great significance to improve LHCD efficiency.
