Codes and datasets associated with the paper "Parameterizing the Energy Dissipation Rate in Stably Stratified Flows"

Here, you will find some of the codes and datasets utilized in the article: "Parameterizing the Energy Dissipation Rate in Stably Stratified Flows". (https://arxiv.org/abs/2001.02255) 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.
