摘 要:Analysis on velocity distributions of steady, uniform suspended sediment-laden flow in open channels was presented. The sediment particle-particle interactions and the buoyancy effects due to density stratification were taken into account through a water sediment mixture s constitute relationship and an adapted Monin-Obukhov length scale to validate the theory for a wider spectrum of sediment concentrations. The developed model with the same Von Karman coefficient as that of a single phase flow was shown to be in the excellent agreement with the measurement results in the controlled experiments with both the low and heavy sediment concentrations.
