RANS and DNS simulations of flow over 2D periodically arranged hills

The data consists of 3 different sets of simulations. - 7 DNS simulations of the flow over 2D periodically arranged hills - 30 RANS simulations of the flow over 2D periodically arranged hills. Variability in the hill geometry is introduced using two parameters, namely the hill steepness angle and the hill streamwise separation.本数据集包含3组不同的数值仿真集合。其中包含7组针对二维周期性排列山丘绕流的直接数值模拟（Direct Numerical Simulation，DNS），以及30组针对二维周期性排列山丘绕流的雷诺平均Navier-Stokes（RANS）模拟。本数据集通过两个参数引入山丘几何形状的可变性，具体为山丘坡度角与山丘沿流向间距。
