The Research on Application of Deflt-3D Software Simulate characteristics of flow in Xinjizhou Distributaries channel
Abstract:In this paper, deflt-3d software is applied, the finite difference method is used , the model focuses on the basic equation of motion, select the appropriate calculation of the grid to be divided, to establish Xinjizhou plane two-dimensional mathematical model of flow. Calculations of flow are verified at the same time, verify the results with the actual line with the better to prove that model can better simulate Xinjizhou distributaries channel of the situation of water sport, and an analysis of distributaries channel of flow characteristics under the natural state, technical reference is provied of the next step improvement of distributaries channe .
Keywords: Deflt-3D software numerical simulation distributaries channel flow characteristics
