Turbulence closure models are central to a good deal of applied computational fluid dynamical analysis. Closure modeling endures as a productive area of research. This review covers recent developments in elliptic relaxation and elliptic blending models, unified rotation and curvature corrections, transition prediction, hybrid simulation, and data-driven methods. The focus is on closure models in which transport equations are solved for scalar variables, such as the turbulent kinetic energy, a timescale, or a measure of anisotropy. Algebraic constitutive representations are reviewed for their role in relating scalar closures to the Reynolds stress tensor. Seamless and nonzonal methods, which invoke a single closure model, are reviewed, especially detached eddy simulation (DES) and adaptive DES. Other topics surveyed include data-driven modeling and intermittency and laminar fluctuation models for transition prediction. The review concludes with an outlook.

湍流闭合建模的一些最新进展

湍流闭合模型是大量应用计算流体动力学分析的核心。闭包建模一直是一个富有成效的研究领域。这篇综述涵盖了椭圆松弛和椭圆混合模型、统一旋转和曲率校正、过渡预测、混合模拟和数据驱动方法的最新发展。重点是闭合模型,在该模型中,针对标量变量(例如湍流动能、时间尺度或各向异性的度量)求解输运方程。回顾了代数本构表示在将标量闭包与雷诺应力张量相关联中的作用。回顾了调用单个闭合模型的无缝和非区域方法,特别是分离涡流模拟 (DES) 和自适应 DES。调查的其他主题包括数据驱动建模和用于过渡预测的间歇性和层流波动模型。审查以展望结束。
