| Abstract: | The 2-D current mathematical model was given on the basis of 2-D fluid dynamical equations. The finite volume method and the full implicit formation in five diagonals were adopted in the computed formation, the method of mosaic grids and the varied step grid and the motion boundary were adopted. So the feature of clear physical meaning and rapid convergence and stability and practicality are apparent in this method. Then the problem of how the oblique section is used as the open boundary section and how the tide level in the open boundary is given were researched. Finally,the current numerical method was used for the feasibility research on a certain coast engineering,and testing its reasonability. |
