AI 中文摘要
二维Kolmogorov流是湍流动力学系统图景的常见试验场。在该系统中,已在许多雷诺数和域尺寸下发现了数百个不稳定周期轨道,尽管最充分探索的是在方形$2π\ imes 2π$域上、强迫波数$k=4$、雷诺数$Re=40$的情况。在此,我呈现了该典型参数区域中8952个精确稳态流的目录。这些解提供了一个固定的星座,为湍流和瞬态动力学提供了信息。
英文摘要
Two-dimensional Kolmogorov flow is a common proving ground for the dynamical systems picture of turbulence. Hundreds of unstable periodic orbits have been found for this system across many Reynolds numbers and domain sizes, although the most well explored is Re$=40$ on a square $2π\times 2π$ domain with a forcing wavenumber of $k=4.$ Here I present a catalog of 8952 exact steady states of the flow in this canonical parameter regime. These solutions provide a fixed constellation informing the dynamics of both turbulence and transients.
