The Numerical Simulation Of 1-D And 2-D River On MIKE

Along with the progress of the technology, the study on the character and movement ruleof fluid is going more and more deep. As the fluid is in the section with complex boundaryfigure, the measure for it is very hard. In addition, due to the limitation of physical model test,the experiment can only afford the parameter for whole flow, while the numerical simulationcan offer the detailed information for correlative flow. Because of the strongpoints innumerical simulation, it has become an effective means for hydrodynamics.The paper studies the MIKE software which has a worldwide application exploited byDHI corporation of Danmark. Several issues are simulated. Some valued Results areacquired.The Main Work of the paper is consisted by:(1) The hydrodynamic module of MIKE11 simulates the Biliuhe from the downstreamdam to the estuary including nine branches. The branches are choosed which are based on thetrue circumstance and the demand of the computation. The cases are computed which areconsisted by twenty years flood once plus the maximal tide of the year and twenty years floodonce plus the maximal tide of history.(2) The results computed by MIKE11 are consistent with HydroInfo. The conclusionobtaineded by Hydroinfo are applied to the actual project.(3) The hydrodynamic module of MIKE21 simulates the plan of a 2-D partial dam-break.The results agree well with literatures. it concludes MIKE21 can solve strong discontinuity.Second,the hydrodynamic module of MIKE21 simulates one river.Post process can show thewater depth contours and flow field etc.
