An ion temperature anisotropy model including cross-field drifts has been implemented in the 2D transport code UEDGE. Two ion temperature equations are solved in the model to give separate ion temperatures perpendicular and parallel to the magnetic field, which results in an additional mirror force for ion parallel transport and also leads to an additional curvature drift in the perpendicular direction. In our previous work, an ion temperature anisotropy model was implemented and applied to the full 2D version of UEDGE including recycled neutrals. The simulation results showed that the mirror force due to anisotropy reduces ion parallel flow velocity, however, the simulations were presented without cross-field electric and magnetic drifts. Nevertheless, in present medium-size tokamaks or future compact fusion devices, cross-fields are important. In this work, the anisotropy model is extended to be compatible with the inclusion of cross-field drifts. Preliminary results on comparison between the model solutions with and without cross-field drifts are presented.

刮除层中具有交叉场漂移的离子温度各向异性模型

包含跨场漂移的离子温度各向异性模型已在二维传输代码 UEDGE 中实现。在模型中求解了两个离子温度方程，以给出垂直和平行于磁场的单独离子温度，从而为离子平行传输产生额外的镜像力，并导致垂直方向上的额外曲率漂移。在我们之前的工作中，实施了离子温度各向异性模型并将其应用于完整的 2D 版本的 UEDGE，包括回收的中性粒子。模拟结果表明，由于各向异性引起的镜面力降低了离子平行流速，但是，模拟没有交叉场电场和磁漂移。然而，在目前的中型托卡马克或未来的紧凑型聚变装置中，交叉场很重要。在这项工作中，各向异性模型被扩展为与跨场漂移兼容。给出了有和没有跨场漂移的模型解决方案之间比较的初步结果。
