Abstract
Two-dimensional numerical simulations of falling liquid film on a vertical wall with and without some artificial velocity oscillations have been performed in order to investigate the relationship between the interfacial wave behavior and heat transfer. Fully developed two-dimensional wave consists of a solitary and a capillary wave. Numerical results indicate that the heat transfer of falling film flow is enhanced by small vortices between the solitary and capillary waves in addition to the well-known flow recirculation in the solitary wave. Resulting from these findings, the heat transfer of the falling liquid film flow can be controlled by the artificial oscillation of the film flow.
