【Abstract】 The wave diffraction in a diagonal current around a large-scale vertical circular cylinder is studied numerically in this paper. The wave relative frequency in the coordinate system moving with current and the angle between the direction of wave propagation and that of current are computed based on the wave dispersion relation. The current field is computed by solving the shallow water equation. The wave field is computed by solving the Mild Slope Equation that has taken the current’s affect into account. The coupling result is obtained by iterative calculation of above two fields. A numerical model is established using a Finite Element Method for simulating the wave diffraction in a current around a large-scale vertical circular cylinder.更多还原
