WMLES results for channel flow and flat plate TBL using Nek5000

This dataset accompanies the following paper:The results are divided into channel flow and zpgtbl. Most data are in hdf5 format, and the contents can be explored via direct interrogation of the hdf5 in your favourite programming language.<br>For zpgtbl, 3 .hdf5 files corresponding to the 3 meshes are provided. For channel flow, the tr_ prefix indicates the Neumann boundary condition, the vs_ the viscosity-based. Then, vrm indicates the Vreman model and sigma the Sigma model. The time_averaging folder contains results for the averaged wall model input. The number after "n" in the file name indicates the number of time-steps the input is averaged across. Finally, the time_spectrum.npy holds the PSD of the velocity signal, as seen in the paper.<br>Additionally, we provide a packed version of Nek5000 and the KTH_Toolbox, which were used to produce the results. These are found under simulation_codes. For wall modelling, https://github.com/timofeymukha/nekwmles was used. An example channel flow case can be found in that repository and is a great starting point for reproducing these results.本数据集配套以下学术论文：研究结果分为槽道流（channel flow）与zpgtbl两类。绝大多数数据采用HDF5格式，可通过您偏好的编程语言直接读取HDF5文件以探索其内容。针对zpgtbl，我们提供了3个对应三种网格的HDF5文件。针对槽道流，文件名前缀tr_代表诺伊曼（Neumann）边界条件，vs_代表基于粘度的设置；其中vrm代表Vreman模型，sigma代表Sigma模型。time_averaging文件夹存储了壁面模型输入经时间平均后的结果。文件名中"n"后的数字代表输入进行平均所采用的时间步数。最后，time_spectrum.npy文件存储了本文提及的速度信号功率谱密度（PSD, Power Spectral Density）。此外，我们提供了用于生成本数据集结果的Nek5000与KTH_Toolbox打包版本，该文件位于simulation_codes目录下。壁面建模相关实现采用了https://github.com/timofeymukha/nekwmles 开源仓库中的代码。该仓库中包含一个槽道流示例案例，可作为复现本数据集结果的良好起点。
