本文采用计算实例对通过波动方程计算浅水环流的有限元方法做了较为深入的研究。研究着重在计算精度、所用CPU时间与所取空间步长、时间步长的关系以及Courant数的取值等方面。计算结果也验证了该方法对抑制短波振荡的有效性。

The numerical simulation of tidal flow has been developed greatly with the development of computer techniques in the past two decades. The generalized wave equation finite-element method is a relatively new numerical model for studying shallow water flow . This method was used to simulate tidal waves of the Gulf of St. Lawrence in Canada . The very good agreement of the numerical results with the field data indicated that the model is an effective and promising numerical method for solving two-dimensional tidal wave problems . 展开更多
