摘要
给出了对流方程、对流扩散方程及长重力波方程的节点正、反计算顺序交替进行的计算格式和上述几种方程这一格式的稳定性和相容性证明。最后,介绍了用交序法计算二维非线性近海潮波的结果。
The ACS is also called ADE method which was first proposed by Saul 'yev (1957) to numerically solve diffusion equation, and later be summed up by Roach (1976).It not only of the advantage of explicit computation but also is unconditional stable. In this thesis, ACS method is used to solve several other kinds of equations including advection equation, advection-diffusion equation and long gravity wave equation. It is proved that for these linear equations the ACS numerical models are also unconditional style. With the ACS, M2 tidal wave of Bohai Sea has been computed, and the results are shown in this paer.
