Data supporting "Optimal mixing in two-dimensional stratified plane Poiseuille flow at finite Peclet and Richardson numbers"

Data supporting publication. Contains codes to create data, initial conditions and figure files, as well as original paper and explanatory "note". Optimization.m : Main routine for optimization (use param.m to specify the flow parameters, mixing norms, resolution etc.) Diagnostic_diag.m : Main routine for diagnostic (forward integration in time only). Use param.m again. The *_diag.m routines are called for diagnostic only. Flow_measures.m and Flow_measures_diag.m contain the definitions of all the diagnostic variables. Their timeseries are stored in norms_timeseries.mat. All the figures have been produced with the data stored in norms_timeseries.mat and the flow snapshots. Omega0.mat is produced by Diagnostic_diag.m and contains the initial vorticity field for the perturbation.

本数据集为发表论文的配套支撑数据，包含数据集生成代码、初始条件文件、图像文件，以及论文原稿与说明性注释文档。Optimization.m：优化主程序（可通过param.m配置流动参数、混合范数、分辨率等相关设置）。Diagnostic_diag.m：诊断分析主程序（仅支持时间正向积分），同样需借助param.m完成参数配置。所有带*_diag.m后缀的程序仅用于诊断分析环节。Flow_measures.m与Flow_measures_diag.m涵盖所有诊断变量的定义，其时间序列数据存储于norms_timeseries.mat文件中。本数据集所有配图均基于norms_timeseries.mat存储的数据与流动快照生成。Omega0.mat由Diagnostic_diag.m生成，存储用于扰动模拟的初始涡量场。
