Direct numerical simulation dataset of turbulent square duct flow

The dataset include mean flow data of square duct flow up to friction Reynolds number 1000 obtained from direct numerical simulation. The dataset also include coefficients obtained from Pope's generalized eddy viscosity framework, for different truncation of the polynomial expansion.

本数据集包含通过直接数值模拟（Direct Numerical Simulation）获得的摩擦雷诺数最高达1000的方形管道流动平均流场数据。此外，数据集还涵盖基于波普（Pope）广义涡粘框架，针对多项式展开不同截断形式所得到的系数。
