Abstract

The results of heat and particle transport simulations for ohmic plasma in the T-10 tokamak with a circular limiter and for D-shaped plasma in the COMPASS tokamak with a divertor are presented. In addition, the H-mode with ohmic heating and with additional heating by the neutral beam injection (NBI) in the COMPASS was simulated. The simulations were carried out with the Canonical profile transport model (CPTM) using the ASTRA code. The obtained electron temperature and density profiles agree with the measured ones with standard deviations within the experimental accuracy of 10–15%. The calculations demonstrated very similar density profiles in the H-mode both with the ohmic and with additional NBI heating. The electron temperature profiles in the H-mode with additional heating have higher pedestals than in the ohmic H-mode, that agree with the measurements. The comparison showed that the ohmic regimes in COMPASS and T-10 can be described by the same stiffness coefficients in the heat and particle transport equations.

基于典型剖面输运模型的COMPASS和T-10托卡马克热和粒子输运模拟

本文给出了T-10型圆形限制器托卡马克欧姆等离子体和COMPASS型导流器托卡马克d形等离子体的热输运和粒子输运模拟结果。此外，还模拟了COMPASS中欧姆加热和中性束注入（NBI）附加加热的h模。采用规范剖面传输模型（CPTM），利用ASTRA代码进行了仿真。得到的电子温度和密度分布与实测值基本一致，其标准差在10-15%的实验精度范围内。计算表明，在欧姆和额外的NBI加热下，h模式下的密度分布非常相似。在附加加热的h模式下，电子温度分布比在欧姆h模式下有更高的基座，这与测量结果一致。对比表明，COMPASS和T-10的欧姆区可以用热输运方程和粒子输运方程中相同的刚度系数来描述。
