Based on the Navier Stokes equation and a modified k ε turbulence model, the transformation of Cnoidal waves over a submerged bar is simulated in this paper. The modified VOF method is adopted to deal with free surface. The governing equation for the volume of fluid is solved by donor acceptor method. A partial cell parameter is introduced to treat irregular boundary,which is based on the finite difference method. In the areas close to the boundary,the technique of wall function is adopted to solve the effect of the wall surface. The surface transformation of Cnoidal waves over the submerged bar is reproduced successfully by the numerical simulation.
