Influence of sewer sediments on flow friction and shear stress distribution

Artikel i vetenskaplig tidskrift, 1995

Most sewers contain more or less deposited sediments. The paper discusses the distribution of the boundary shear stresses and the hydraulic resistance in part-full sewer pipes with such deposited sediments. The discussion is based on a series of numerical experiments using a validated numerical turbulence model. The results from the numerical model are compared with the sidewall elimination method. The validity of the sidewall elimination method is evaluated.
