Abstract: The turbulence anisotropy in flow over noncohesive sediment beds at an entrainment threshold, as compared to that over immobile beds, is studied. The streamwise component of anisotropy tensor in near-bed flow for threshold ...

Abstract: This experimental study is devoted to quantification of the near-bed turbulence characteristics at an entrainment threshold of noncohesive sediments. Near the bed, the departure in the distributions of the observed ...

Abstract: The time-averaged characteristics of turbulent wall-wake flows downstream of a sphere placed on a rough wall are studied. The profiles of the defect of streamwise velocity, Reynolds shear stress, and turbulence intensities ...
