| Abstract | Direct numerical simulation results are presented for sediment-laden turbulent channel flow. The focus of the work is on the stratification effects on velocity and concentration profiles. The results show that the inner linear law and logarithmic law are still present for flows stratified by suspended sediment as long as the flow does not relaminarizes. The inner linear law is not modified by the presence of suspended sediment. The logarithmic law, however, shows appreciable change of the slope with stratification. The change of slope is associated to a decrease of the apparent von Karman constant, which can be explained in terms of the variation of the Monin-Obukov scale in the near-wall region. ena associated to sediment transport processes with the hope that they will shed some light on the understanding and development of closure strategies and empirical relations employed in larger scale modeling approaches such as Reynolds Averaged Navier-Stokes (RANS) and shallow water models. 2 MATHEMATICAL AND NUMERICAL |
