在充分发展的粗糙壁槽道流的流向速度统计已超过砂砾和网格类型的表面拓扑结构进行了研究。流动被证明是充分发展和二维的四阶矩的速度。虽然这两种表面类型的流动似乎表现出有限的对数区域，网格表面的内部和外部缩放区域未能重叠。讨论了网格展向周期性对外尺度的影响。
The streamwise velocity statistics in fully-developed rough-wall channel flow have been investigated over grit- and mesh-type surface topologies. The flow was demonstrated to be fully-developed and two-dimensional up to the fourth moment of velocity. Though the flow over both surface types appear to exhibit a limited logarithmic region, the regions of inner and outer scaling over the mesh surface fail to overlap. The influence of the spanwise periodicity of the mesh upon the outer scaling is discussed.
