Data underlying the publication Direct numerical simulation of supersonic turbulent flows over rough surfaces

Direct numerical simulation dataset of supersonic turbulent channel flow over rough walls. The dataset comprises both smooth and rough wall cases, spanning friction Reynolds numbers 500-1000 and bulk Mach numbers M_b = 0.3--4. <br> The dataset contains mean flow statistics of the direct numerical simulation in the reference publication: D. Modesti, S. Sathyanarayana, F. Salvadore, M. Bernardini "Direct numerical simulation of supersonic turbulent flows over rough surfaces" J. Fluid Mech. 2022粗糙壁面超音速湍流槽道流动直接数值模拟（Direct Numerical Simulation）数据集。本数据集涵盖光滑壁面与粗糙壁面两类工况，摩擦雷诺数覆盖区间为500至1000，体马赫数M_b取值范围为0.3~4。 本数据集包含参考文献中该直接数值模拟的平均流场统计量，参考文献详情如下：D. Modesti、S. Sathyanarayana、F.
