Abstract


With the continuous advancement of science and technology , will continue in - depth research on the nature and the law of motion of the fluid . The same time , due to the fluid motion is extremely complex , people know it is there are significant limitations . Although the physical model test is to study the common means of fluid movement , but for the flow within the complex shape of the boundary section present in large amounts in the actual engineering , given its complexity and measurement difficulties , experiments are often only give a total flow parameter, information section of the flow field are not given in detail , and numerical simulation of flow field can be given specific information . Precisely because of the numerical simulation has more advantages , gradually has become a powerful means to study fluid dynamics . This paper in the world within the Danish DHI MIKE software developed by a large number of applications , the following can numerical simulation , made ??some valuable results . The main work includes . ( 1 ) Application MIKE11 hydrodynamic module to calculate the the Biliu River Reservoir dam downstream to the estuary , including the passing of the nine tributaries . Tributaries of tributaries representative is selected according to the real situation , as well as computing needs , were Biliuhe year return period flood plus years the tide and a case of two decades plus historical wave calculation of the two conditions . ( 2 ) the MIKE11 water dynamics module calculates and library groups - the flow of drainage system in the general program HydroInfo calculated results (already applied to actual engineering ) were compared to results in good agreement . ( 3 ) should MIKE21 hydrodynamic module of the classic two-dimensional dam break numerical simulation results are relatively good agreement with the literature , we can draw MIKE21 can solve the strong discontinuity point . Again use MIKE21 hydrodynamic module for the numerical simulation of a river , the river flow field contour visualization results .
