Influence of the Suspended Sediment Concentration on the Calculation of the Vertical Distribution of Streamwise Velocity
The primary objective of this study was to investigate the vertical distribution of streamwise velocity in open-channel flow carrying sediments. The governing equations encompassing mass and momentum balances for the fluid are employed, with the Reynolds stress term linked to the mixing length of the flow, which is treated as a function of concentration. Both wall-normal and settling velocities are considered as functions of concentration. Notably, a concentration-dependent von Kármán constant, incorporating the effect of suspended sediment particles, is utilized in the mixing length expression, rendering the model more realistic. The resultant nonlinear ordinary differential equations are solved numerically. The model was analyzed for particle-free flow, wherein the concentration term was set to zero. The deviation of the velocity profile in this scenario from the original scenario with concentration underscores the significance of incorporating the concentration term in the study of velocity models in sediment-laden flows. Additionally, the developed velocity model was validated against pertinent experimental data available in the literature. Subsequent error analysis was conducted to compare the model with experimental data.
