ON ACCURACY FOR FINITE DIFFERENTIAL CALCULATION OF TWO DIMENSIONAL WATER WAVES

To accurately calculate two dimensional water waves using the finite differential method, parameters controlling calculated results should be suitably selected. This paper deals with the effects of numerical parameters controlling calculated wave profiles such as minimum spacing of grid, time increment and Reynolds number. Numerical computation by the finite differential scheme was applied to the two dimensional wave problem generated by the moving pressure disturbance on the water surface. The computational scheme used is similar to the MAC method. The characteristics of this computational method are that the two-dimensional Navier- Stokes equations are treated including viscosity terms, and the body fitted coordinate system and the staggered mesh system are adopted.
