| In this paper, the water flow movement and sediment transport of the energy and chemical base water supply project Shuidonggou reservoir located in Inner Mongolia Etuokeqianqi Shanghaimiao was simulated numerically and analyzed experimentally.Use GPS-RTK measurement system and acoustic Doppler current profiler for Shuidonggou reservoir were set up and cross sectional flow velocity, water depth, sediment and water table measured. The measured cross-section curve fitting depth data were analyzed each section width and depth of the water location trends; the twice measured cross-section of typical reservoir bottom elevations were compared to analyze the erosion and deposition conditions such as the location and extent of erosion and deposition. Section method applied to calculate the water level of the reservoir under different storage capacity and storage capacity curve plotted. To set the pile point elevation and reservoir bottom elevation data, using interpolation method draws the reservoir bottom elevation contour map library and reservoirs3D illustration.Zero-equation model is adopted to establish a two-dimensional flow and sediment mathematical model, detailing the Delaunay triangulation mesh method and encryption algorithms, and a numerical example shows that the method can effectively control the density of the generated mesh. The finite volume method for general discrete equation, and gives the SIMPLEC method on unstructured grid implementation process.Using the mathematical model used in this paper, we simulate the flow field of three typical reservoir conditions with two-dimensional numerical simulation. The typical cross-section of the reservoir bottom elevation and vertical mean velocity analog value and the measured results were compared and analyzed. The results show that both more consistent description herein established2D mathematical model and numerical method used is reasonable, to be more accurate reservoir for Shuidonggou2D mathematical model was simulated. |
