Abstract

The effects of resonant flow case, on the nonlinear surface waves of film with uneven bottom were analyzed. From the potential flow theory, fKdV equation for the nonlinear surface wave was obtained by perturbation technique. The simulation has been made by pseudo-spectral method, and the waterfall plot of the surface wave was draw with Matlab. The flow is an incompressible, inviscid fluid with surface tension and different boundary; the results show that the different boundary: the positive boundary, the negative boundary has different effect on the film surface wave.
