摘要

在多组分边缘流体代码 SOLEDGE3X 的二维传输版本中引入了 W 杂质。为此，采用了几种物理成分。首先，使用 Garcia-Rosales 公式计算 W 的总侵蚀量，然后使用 Groth-Tskhakaya 公式或根据动力学模型的再沉积数据训练的神经网络估算 W 的再沉积量。这种流体 W 传输方法与ERO2.0 在边缘域和 SOL 域获得的动力学结果进行了比较。此外，由于 W 主要在核心区域辐射，而 SOLEDGE3X 迄今为止尚未解决这一问题，因此针对核心等离子体区域实施了一个假定极对称的一维模型。此外，还讨论了氧杂质对 W 含量的影响（尤其包括 W 氧化层对全氟化碳的影响）。图中显示了该模型在氘等离子体与氧和钨之间的一些应用，并考虑了氧对钨的溅射。

SOLEDGE3X integrated core-edge modelling of tungsten sources, migration, and radiation in WEST plasmas

The W impurity species was introduced in the multi-component edge fluid code SOLEDGE3X, in its 2D transport version. To do so, several physical ingredients have been implemented. Firstly, W gross erosion is calculated using the Garcia-Rosales formula, and W re-deposition is estimated with either a Groth–Tskhakaya formulation or a Neural Network trained on re-deposition data from a kinetic model. This fluid approach for W transport is compared with kinetic results obtained with ERO2.0 in edge and SOL domains. Moreover, as W radiates mainly in the core region, which was thus far not resolved in SOLEDGE3X, a 1D model has been implemented for the core plasma region assuming poloidal symmetry. The impact of Oxygen impurities on W content is also addressed (including in particular the impact of W oxide layers on the PFCs). A few applications of the model implementing a Deuterium plasma with Oxygen and Tungsten, taking into account the sputtering of Tungsten by Oxygen are shown.
