Codes and datasets associated with the paper "On the dissipation rate of temperature fluctuations in stably stratified flows"

Here, you will find some of the codes and datasets utilized in the article: "On the dissipation rate of temperature fluctuations in stably stratified flows". (https://arxiv.org/abs/2001.06369) The direct numerical simulations were performed using the HERCULES code (https://github.com/friedenhe/HERCULES). For all the simulations, the bulk Reynolds number is kept at 20,000. The bulk Richardson number is varied from 0.1 to 0.5. The zip files Re20000RiXX.zip contains the various turbulence statistics. Re20000Ri10: Ri_b = 0.1 Re20000Ri20: Ri_b = 0.2 Re20000Ri30: Ri_b = 0.3 Re20000Ri40: Ri_b = 0.4 Re20000Ri50: Ri_b = 0.5 Every dat file (within the zip archives) is in ascii format and has 10 rows and 286 columns. Each row corresponds to normalized time (ranging from 1 to 10). Each column represents vertical model levels.本文收录了论文《关于稳定分层流动中温度脉动的耗散率》（On the dissipation rate of temperature fluctuations in stably stratified flows）所使用的部分代码与数据集。论文链接：https://arxiv.org/abs/2001.06369 所有直接数值模拟均通过HERCULES代码完成，代码仓库链接：https://github.com/friedenhe/HERCULES。本次模拟的整体雷诺数固定为20000，整体理查森数的取值范围为0.1至0.5。 命名为Re20000RiXX.zip的压缩文件内含各类湍流统计数据，各压缩包对应的整体理查森数如下：Re20000Ri10对应Ri_b=0.1；Re20000Ri20对应Ri_b=0.2；Re20000Ri30对应Ri_b=0.3；Re20000Ri40对应Ri_b=0.4；Re20000Ri50对应Ri_b=0.5。 每个压缩包内的.dat文件均采用ASCII格式，包含10行286列数据。其中每一行对应归一化后的时刻（取值区间为1至10），每一列对应垂直模型层级。
