摘要
本文首先概述湍流低维动力系统的理论与实验背景,分析POD方法的优、缺点,及其数学基础和发展。然后,着重介绍流动数据库分析及建立低维动力系统的优化理论。
The theoretical and experimental backgrounds of the low-dimensional dynamical systems of turbulence are reviewed. The advantages and shortcomings, the mathematical background of the POD method and its developments are outlined. Then emphasis is put on the optimal theory on flow database analysis and construction of low-dimensional dynamical systems.
