An experimental study was conducted to investigate turbulent flow of water over a cuttings bed by use of a large-scale horizontal-flow loop. A nonintrusive laser-based-imaging technique was used to determine instantaneous local velocity near the stationary sandbed/fluid interface in the horizontal annulus. The velocity measured directly at the sandbed/fluid interface was then used for critical evaluation of the accuracy of the assumptions and correlations commonly used for development of mechanistic and semimechanistic sediment-transport models. In particular, effects of turbulent velocity fluctuations on the magnitude of the hydrodynamic drag and lift forces and the interfacial (bed) shear stress are investigated.
