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.

本数据集源于强制对流平面槽道流动的直接数值模拟（Direct Numerical Simulation）所得到的平均流动统计量。该数据集包含20个流动工况，所有工况的体平均马赫数均为0.2，摩擦雷诺数最高可达3000，覆盖多组体平均-壁面温度比工况，涵盖壁面加热与壁面冷却两类算例。平均流动统计量包含平均动量平衡与热平衡的剖面数据，这些剖面已在流动均匀方向与时间维度上完成统计平均。平均剖面数据还辅以摩擦系数与对流换热系数。数据集按照参考文献表1中所列的流动工况名称创建对应文件夹进行存储。
