发展了一种新的基于理论的输运模型，该模型具有综合物理(囚禁、一般环面几何、完全电磁、电子-离子碰撞、杂质离子)。该模型的核心是新的捕获-陀螺-朗道流体(TGLF)方程，它提供了旋动力学漂移波不稳定性(捕获离子和电子模、离子和电子温度梯度模以及动力学气球模)的线性本征模的快速而精确的近似。与其前身GLF23相比，新的TGLF传输模型更准确，并且具有更大的有效范围。TGLF模型统一了一组陀螺-朗道-流体方程中捕获和通过的粒子。一种捕获粒子平均朗道共振的模型使方程在从捕获离子模到电子温度梯度模的整个漂移波波数范围内无缝地工作。一种快速的本征模解方法使无限制的磁几何成为可能。运输模型使用..。
A new theory-based transport model with comprehensive physics (trapping, general toroidal geometry, fully electromagnetic, electron-ion collisions, impurity ions) has been developed. The core of the model is the new trapped-gyro-Landau-fluid (TGLF) equations, which provide a fast and accurate approximation to the linear eigenmodes for gyrokinetic drift-wave instabilities (trapped ion and electron modes, ion and electron temperature gradient modes, and kinetic ballooning modes). The new TGLF transport model is more accurate, and has an extended range of validity, compared to its predecessor GLF23. The TGLF model unifies trapped and passing particles in a single set of gyro-Landau-fluid equations. A model for the averaging of the Landau resonance by the trapped particles makes the equations work seamlessly over the whole drift-wave wave-number range from trapped ion modes to electron temperature gradient modes. A fast eigenmode solution method enables unrestricted magnetic geometry. The transport model uses...
