چکیده مقاله:
In this paper, we consider numerical modeling of flow in 90° intersections of open channels. The modeling is based on finite volume solution of the shallow water equations (St. Vnant equations). The method used is upwind based with first order accuracy in space and time. For networking of solution space the unstructured triangular cells have been used. In numerical tests, flow parameters such as discharge distribution in channels, length of the flow separation zone, and possible jump locations have been obtained. The comparison of the results with experimental data shows the proper prediction ability of the numerical method used. Using the numerical effort applied, we investigated the flow distribution in channels based on inflow Froude number and the roughness effect on vortex length in lateral branch.
