Abstract
Two- and three-dimensional numerical simulations of falling liquid film on a vertical wall 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 waves. 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. Three-dimensional simulation results indicate the importance of relationship between the surface wave structure and the wall shear stress.
