论文摘要
先前针对第一原则的集成建模的研究表明，ETG湍流可能导致射流高性能混合H模式场景中的抗gyrobohm同位素缩放。针对高保真湍流建模的专门比较研究使这一主张无效。带有磁场扰动的离子尺度湍流，可以匹配温度梯度误差边缘内的功率平衡通量。来自两个不同代码的多尺度陀螺仪模拟不会产生明显的ETG热通量，这表明简单的大脑规则是其发作的足够标准。
Previous studies with first-principle-based integrated modelling suggested that ETG turbulence may lead to an anti-GyroBohm isotope scaling in JET high-performance hybrid H-mode scenarios. A dedicated comparison study against higher-fidelity turbulence modelling invalidates this claim. Ion-scale turbulence with magnetic field perturbations included, can match the power balance fluxes within temperature gradient error margins. Multiscale gyrokinetic simulations from two distinct codes produce no significant ETG heat flux, demonstrating that simple rules-of-thumb are insufficient criteria for its onset.
