| Abstract: | Detailed experimental measurements were conducted for drag-reducing flows over muddy beds with different density. Mean velocity distribution, coefficient of friction, turbulence intensity, bursting period and energy spectrum are given and compared with those of flows over a fixed bed. The results show muddy beds can cause drag reduction or velocity increase, and suppress production of turbulent bursts and dissipation of turbulent energy. |
