Nonlinear Waves in a Falling Film with Phase Transition

Abstract eng:
Intensive investigation of thin liquid films is caused by their wide application in engineering. In the majority of practical situations the film flow is unstable and waves develop on the liquid surface. It is known that the waves in liquid film intensify processes of heat and mass transfer even for laminar flow. Wave generation and transport processes in falling liquid films without phase transition were investigated in many studies; the results of these studies are summarized in [l]. The wave dynamics and heat transfer in non- isothermal films are much less studied. The purpose of the presented research is to study the nonlinear evolution of waves in the film with a phase transition, and to determine the effect of waves on heat transfer. Nonlinear evolution of the two-dimensional both natural and forced waves in a liquid film is studied by numerical method. An integral-boundary-layer model [2] modified to consideration of phase transition is applied to describing nonlinear waves in a liquid film.
