国内外有哪些流体力学经典著作？ - TurbPhys的回答 - 知乎 https://www.zhihu.com/question/335644582/answer/822877093
Sjunnesson, A, Nelsson, C, and Max, E. 1991. "LDA measurements of velocities and turbulence in a bluff body stabilized flame." Sweden. sci-hub，researchGate，已经试过了，求助各位大佬是否有方法能下载到:xinxin:
@veen 不清楚，cfl只是说保证计算结果收敛，精度的问题可能重点不在这上面了，稳态计算的话cfl要求没那么高
@veen 多谢大佬！^O^/
在方柱计算中，对升力系数进行FFT分析，取样数据点在10000左右，得到如下结果，主频与实验较为吻合，在高频处出现谐振，是由于方柱前缘分离剪切层中K-H不稳定性导致的升力系数高频振荡吗？谐振又是怎么产生的呢？ 诚心向各位前辈请教，求指导！ FFT Power.jpg
