Title: | Sediment Concentration And Turbulent Boundary Layer of Wave-Induced Sheet Flow | Authors: | Tai-Wen Hsu Hsien-Kuo Chang |
Keywords: | sheet flow;boundary layer | Issue Date: | 1999 | Publisher: | International Society of Offshore and Polar Engineers | Journal Volume: | 32 | Journal Issue: | 5 | Start page/Pages: | pp. 675-688 | Source: | The Ninth International Offshore and Polar Engineering Conference | Abstract: | A turbulence model describing sediment concentration and turbulent boundary layer of wave-induced sheet flow is presented. The simultaneous interactions between oscillatory, turbulent flow, and suspended sediment are considered. The model specifies the equivalent roughness as a function of Shields parameter, which is varying with time and is more physically realistic over a mobile fiat bed. The model appears to be verified as well as existing data permits. An estimate of resulting turbulent boundary layer and sediment concentration for different choices of the equivalent roughness is given. The wave friction factor which differs from the conventional rough wall law is obtained from the integration of the momentum equation. |
