Direct simulation of hot jet in cold channel crossflow with temperature mixing

This is the data of a direct simulation of a hot jet in cold channel crossflow. Three thermal boundary conditions are considered: T=0 at the wall [1], Q=0 at the wall [1, 2] and conjugate heat transfer [3] For details about the computational configurations, methods and results, please refer to [1-3] (see links below) A paper on validating selected RANS models using the current database has been submitted to International Journal of Heat and Fluid Flow. A paper discussing the coherent structures of current flow using proper orthogonal decomposition (POD) and dynamic mode decomposition (DMD) has been submitted to Journal of Fluid Mechanics. We have the 3D time-averaged statistics of mean velocity, Reynolds stress, heat fluxes, temperature fluctuations and their budgets. We also have more than 4000 full resolution instantaneous snapshots for each case (only 200 for the adiabatic case). The complete dataset is about 20TB!!! More data will be released in the future. Please feel free to contact me if you need more information or more data.

本数据集为冷通道横流中热射流的直接数值模拟（Direct Numerical Simulation, DNS）数据。本研究共设置三类热边界条件：壁面恒温为0（T=0）[1]、壁面绝热热流为0（Q=0）[1,2]以及共轭换热[3]。有关计算配置、数值方法与结果的详细说明，请参阅文献[1-3]（链接见下文）。
依托本数据集开展选定雷诺平均Navier-Stokes（Reynolds-Averaged Navier-Stokes, RANS）模型验证的研究论文已投稿至《International Journal of Heat and Fluid Flow》；采用本征正交分解（Proper Orthogonal Decomposition, POD）与动态模态分解（Dynamic Mode Decomposition, DMD）分析本流场相干结构的研究论文已投稿至《Journal of Fluid Mechanics》。
本数据集包含三维时均统计量数据，涵盖平均速度、雷诺应力、热通量、温度脉动及其各收支项。各工况均包含超过4000组全分辨率瞬时流场快照（绝热工况仅提供200组快照）。完整数据集总容量约为20TB！后续将陆续发布更多相关数据。若需获取更多信息或拓展数据集，请随时与我们联系。
