Abstract

The linear stability of condensate film flowing on an inclined isothermal plate under action of gravity and turbulent vapor flow was the subject of study. The cases of cocurrent and countercurrent flow of two phases were considered at an arbitrary inclination of the plane. The first part of this work deals with stationary film flow. The impact of vapor flow on the film is described by a given shear stress on the interface with account for the transverse mass flux due to phase transition. The integral method gives the analytical solution for distribution of film thickness along the plane (with and without account for film inertia) at different inclination angles. The second part of paper deals with linear stability of stationary film flow. The fluctuation of shear stress on the surface was calculated using the quasilaminar model. The two-wave equation for film thickness with phase transition and dispersion formulas were derived. The results of effect of condensation on film stability are presented for a wide range of flow parameters.
