摘要

摘要: 将波浪辐射应力与抛物型缓坡方程中的待求变量联系起来,提出了一种计算辐射应力的新方法,并用有限差分法对控制方程进行了数值求解。数值结果表明这种方法精度高、编程简单、求解快速,可用于实际大区域波浪辐射应力的计算。

Abstract: A new method for the solution of wave radiation stresses is proposed by linking wave radiation stresses with the variables in the parabolic mild-slope equation.The governing equations are solved numerically by the finite difference method.Numerical results show that the new model with high accuracy can be efficiently solved with little programming effort,and can be applied to the solution of wave radiation stresses in large coastal areas.
