摘      要：Numerical simulations have been carded out for two-dimensional wavy falling liquid film in order to investigate kinetic energy and surface energy of that liquid film. Governing equations, which are continuity equation, Na-, vier-Stokes equation, and equations of interfacial boundary conditions including surface movement and effect of surface tension, have been solved directly by means of a numerical scheme based on the finite difference method. In most cases, periodic disturbances superimposed at inflow boundary grow to fully developed waves Which retain the given periodic behavior. In some cases, however, random waves appear after the fully developed waves. Variations of kinetic energy and surface energy of the periodically developed waves and the random waves have been discussed.
