scale.微观混和一般指物料从湍流分散后的最小微团(Kolmogorov尺度)到分子尺度上的均匀化过程。2 It has been found that Kolmogorov ′ s 2/ 3 law is satisfied in the range of 0.33~ 1.07 m and outer scale is larger than 20 m in perpendicular direction.结果表明:大气在大于0.33~1...

The Kolmogorov length scale attains higher values in the core of the primary vortex due to low dissipation rate there. A value of 0.01 times the size of the cubic cavity is a good representative value at Re=10000. Even though the present (84×84×84) grid cannot resolve this scale very ...
今天刚和一位老师讨论的这个问题,谈一点粗浅的想法,不一定对。由于湍流脉动的随机性,如果观察的尺度过...
