AI 中文摘要
本文报道了三维边缘等离子体输运代码EMC3-EIRENE在 divertor Tokamak Test（DTT）设施上的实现过程及其首次应用结果，重点是评估离子回旋共振加热（ICRH）天线表面的热负荷。首先利用轴对称几何结构和SOLPS-ITER模拟结果评估EMC3-EIRENE描述轴对称等离子体的性能。接着在三维模拟中纳入ICRH天线结构，假设不同环形对称性以确定能否减少计算量及三维评估与二维近似的偏差程度。得到三维天线热负荷分布预测值，顶板和两侧板峰值分别达0.9、2.1和3.8MW/m²。最后纳入三维气体喷射评估其对天线热负荷的影响，并展示了气体喷射与天线几何结构耦合作用下的三维边缘等离子体行为。
英文摘要
This paper reports on the implementation process of the three-dimensional (3D) edge plasma transport code EMC3-EIRENE on the Divertor Tokamak Test (DTT) facility and the results of its first application, with a focus on assessing the heat load on the Ion Cyclotron Resonance Heating (ICRH) antenna surfaces. Using axisymmetric geometries and the SOLPS-ITER simulation results as a reference, we first evaluate the performance of the EMC3-EIRENE in describing axisymmetric plasmas to ensure correct code modelling setup for later complex 3D applications. We then incorporate the ICRH antenna structure in our 3D simulations, assuming different toroidal symmetry for the antenna to determine whether the heat load assessment can be carried out with reduced computational effort, and to what extent a 3D assessment deviates from a 2D approximation. The predictions of the 3D antenna heat load distribution are obtained and the peak values on the top plate and the two side plates reach 0.9, 2.1 and 3.8 MW/m2, respectively. Finally, 3D gas puffing is included to evaluate its impact on the antenna heat load. The corresponding 3D edge plasma behavior is presented under the coupled effects of gas puffing and the antenna geometrical structure.
