Data underlying the publication `Friction and heat transfer in forced air convection with variable physical properties'

Mean flow statistics from direct numerical simulation of plane channel flow of forced air convection. The dataset features 20 flow cases at bulk Mach number 0.2 and friction Reynolds number up to 3000, spanning several bulk-to-wall temperature ratios, including cases with wall heating and wall cooling. The mean flow statistics include profiles of the mean momentum and thermal balance, averaged in the homogeneous directions and in time. Mean profiles are complemented by friction and heat transfer coefficients. Data are organized in folders named after the flow cases in table 1 of the reference publication.

本数据集源自强制空气对流平面槽道流（plane channel flow）的直接数值模拟（Direct Numerical Simulation, DNS）所得的平均流动统计量。该数据集包含20个流动工况，整体马赫数为0.2，摩擦雷诺数最高达3000，涵盖多种整体-壁面温度比，包含壁面加热与壁面冷却两类工况。平均流动统计量包含平均动量平衡与热平衡的剖面分布，这些剖面通过在流动的均匀方向与时间上进行平均得到。平均剖面还辅以摩擦系数与传热系数。所有数据按照已发表文献表1中所列的流动工况名称，分类存储于对应的文件夹中。
