A Computational Fluid Study of Falling Film Behavior on Flat Plate

In this paper, the 3D numerical simulations on falling film behaviour on flat plate with and without interfacial gas-liquid shear stress are carried out. The film thickness and velocity distribution of water film flow with different Reynolds numbers are studied. The results agree well with the experimental and theoretical data. The influence of the surface wave on film velocity is revealed. The calculations also investigate the effect of gas-liquid shear stress on solitary waves of falling film.Copyright © 2014 by ASME
