WATER AND SEDIMENT TWO-PHASE FLOW TWO-DIMENSIONAL FINITE ELEMENT SOLUTIONS OF THE YELLOW RIVER CHANNEL

摘要

Water and sediment movement numerical simulation is one of the most challenging problems in the two-phase research. Based on the water and sediment two-phase flow basic theory finite element method and the numerical model, the water and sediment movement of the typical wandering Huanyuankou to Jiahetan river reach, one of the key flood control ones in the lower reach of the Yellow River, is simulated and analyzed. From the two-phase parameters such as low water and flood water velocity vector, velocity size isolines, sediment concentration distribution isolines, riverbed deposition and erosion deformation, water level and variation after the given time-process, sediment diffusion transport law and riverbed deformation are disclose.
