| Abstract: | Toward the suitable tidal wave equations, the numerical simulation of flow field of west Dayabay is performed by using the pseudospectral method of parted steps in Chebyshev polynomial. The numerical results indicate that the pseudospectral method of parted steps is more accurate and feasible than general pseudospeetral method to forecast the fluid velocity in short time. |
