碩士 / 國立成功大學 / 水利及海洋工程學系 / 88 / Based on the time-dependent parabolic mild-slope equation, the curvilinear coordinate is used to form the appropriate boundary grid system for wave calculations. The governing equation subject to radiation boundary conditions is solved by alternative direction implicit (ADI) method. From the numerical calculation, the special shape of coastal boundary topography and the problem of wave transformations can be solved by the curvilinear governing equation. In comparison with the finite difference method of Cartesian coordinate, the present model can improve the accuracy of the calculation by adjusting the size of grid mesh and fitting the appropriate grid system for irregular boundaries. The predictions were compared with experimental data and analytical solutions for the cases of wave transformations and waves passing around the circular pile.
