Abstract


NUMERICAL MODELING OF OPEN CHANNEL FLOW WITH H2 WATER SURFACE PROFILES
In open channel flows, 12 different surface profiles are formed depending on the flow conditions. The occur of water surface profiles varies depending on the upstream and downstream water depths, bed slope and the geometric characteristics of the interacted structure. The relation of the measured water depth without any structure with the critical water depth, formed in situation of critical flow, are used in the classification of the flow profiles. Open channel flows with different water surface profiles have been investigated experimentally in detail by researchers. Because of advances in technology in recent years, it is possible to solve governing equations by computational fluid dynamics methods. Computational fluid dynamics methods, which are more economical than experimental models, are frequently used in solving hydraulic problems. In this study, numerical solutions of open channel flow with different water surface profiles are calculated. The turbulence shear stress in numerical modeling is calculated by using the Re- Normalization Group (RNG) model and the water-air intersection is determined by using the Volume of Fluids (VOF) method. Experimental measurements in the literature and numerical model results are compared. The numerical model is found to be successful in determining the water surface, especially in the drop region where H2 profile is formed.
