| Abstract: | The method of the multiple scale is introduced to separate the N-S equation,thus deriving the different scale tidal current. wave equation with the Reynolds separation in approximate variables and solving conditions. By use of mathematical methodology to explain the interaction and influence between the tidal current and wave,the comparison is made between results mentioned above and Reynolds equation by means of analogy. |
| Keywords: | multiple scales tidal current wave separation |
