Abstract

First principle modelling of edge plasma turbulence including neutrals and plasma recycling on the wall remains a challenge, in particular due to the long time scales necessary to simulate to reach particle balance. In this contribution, we propose a strategy to address these long time scales with the fluid code SOLEDGE, resorting to 2D reduced models for turbulence as well as 3D coarse grid simulations. The approach is applied to simulate TCV-X21 reference plasma scenario for edge turbulence modelling validation.
用SOLEDGE3X模拟TCV-X21实验的全局三维全尺寸湍流
边缘等离子体湍流的第一原理建模,包括中性和等离子体在壁上的循环,仍然是一个挑战,特别是由于模拟达到粒子平衡所需的长时间尺度。在这篇文章中,我们提出了一种策略来解决这些长时间尺度的流体代码SOLEDGE,诉诸于湍流的2D简化模型以及3D粗网格模拟。将该方法应用于TCV-X21参考等离子体场景的模拟,验证了边缘湍流模型的有效性。
