基于DUGKS的槽道湍流大涡模拟研究

LARGE EDDY SIMULATION OF TURBULENT CHANNEL FLOW USING DUGKS-LES

摘要: 基于介观数值模拟方法的大涡模拟 (Large Eddy Simulation, LES) 是研究湍流的重要手段之一。离散统一气体动理学方法 (Discrete Unified Gas Kinetic Scheme, DUGKS) 是一种相对较新的介观方法，其作为湍流大涡模拟工具的研究还处于起步阶段。本文通过耦合标准离壁 Smagorinsky 亚格子应力模型和

Abstract: The mesoscopic-scheme-based Large Eddy Simulation (LES) has emerged as an alternative approach to study turbulent flows. The Discrete Unified Gas Kinetic Scheme (DUGKS) is a relatively newly developed mesoscopic method, and the realization of LES in DUGKS is still in its early stages.
