Hydrodynamic Characteristics of Gradually Expanded Channel Flow
In this study, analytical-statistical solutions of the characteristics in gradually expanded channel flows, such as velocity profile, turbulent shear stress profile and profiles of turbulent kinetic energy and energy dissipation rate are derived. Then, the comparisons of the analytical results are made with the results of 2-DH with depth-averaged numerical model solution. Good trends and agreements are obtained, and the expanding angel takes an important and relevant role on the main effect of these hydrodynamic items. These analyticalstatistical solutions can be used for real applications.
