非线性回转动力学代码允许详细了解托卡马克堆芯湍流传输。然而，它们的计算需求排除了它们用于预测性轮廓建模的可能性。需要另一种方法来弥合理论理解和实验预测之间的差距。准线性陀螺动力学模型，QuaLiKiz(Bourdelle等人，2007 Phys.等离子体14,112501)，已被证明足够快，可以简化系统与实验的接口。回顾了该方法的推导和近似。准线性近似在较宽的堆芯等离子体参数范围内被证明是有效的。使用与Cronos集成建模代码相结合的QuaLiKiz进行剖面预测的实例(Artaud等人，2010年Nucl.Fusion 50 043001)。QuaLiKiz正在与其他集成建模平台耦合，如ETS和Jetto。QuaLiKiz准线性陀螺动力学湍流热通量、粒子通量和角动量通量对所有用户都是可用的。它允许广泛的独立解释分析和基于第一原则的综合预测建模。
Nonlinear gyrokinetic codes allow for detailed understanding of tokamak core turbulent transport. However, their computational demand precludes their use for predictive profile modeling. An alternative approach is required to bridge the gap between theoretical understanding and prediction of experiments. A quasilinear gyrokinetic model, QuaLiKiz (Bourdelle et al 2007 Phys. Plasmas 14 112501), is demonstrated to be rapid enough to ease systematic interface with experiments. The derivation and approximation of this approach are reviewed. The quasilinear approximation is proven valid over a wide range of core plasma parameters. Examples of profile prediction using QuaLiKiz coupled to the CRONOS integrated modeling code (Artaud et al 2010 Nucl. Fusion 50 043001) are presented. QuaLiKiz is being coupled to other integrated modeling platforms such as ETS and JETTO. QuaLiKiz quasilinear gyrokinetic turbulent heat, particle and angular momentum fluxes are available to all users. It allows for extensive stand-alone interpretative analysis and for first principle based integrated predictive modeling.
