过渡壁面流动中的大尺度动力学模型

Towards a model of large scale dynamics in transitional wall-bounded flows

Paul Manneville

摘要:

本文提出了一个简化的方程组来处理过渡壁面边界流层流-湍流模式中存在的大尺度流的反馈相互作用,其中小尺度雷诺应力由湍流的自维持过程本身产生,采用Waleffe方法的扩展来模拟(Phys. Fluids 9(1997)883-900),其详细表达作为正文的附件显示。

英文摘要:

A system of simplified equations is proposed to govern the feedback interactions of large-scale flows present in laminar-turbulent patterns of transitional wall-bounded flows, with small-scale Reynolds stresses generated by the self-sustainment process of turbulence itself modeled using an extension of Waleffe's approach (Phys. Fluids 9 (1997) 883-900), the detailed expression of which is displayed as an annex to the main text.
