Analiza powierzchni swobodnej filmu cieczy o złożonych właściwościach reologicznych

The studies presented were focused on the effect of polymers and surfactants additives on changes in the free surface of liquid falling film. The suppression of surface waves and the decrease of the mean film thickness have been observed. Total decay of waves on the free surface in surfactant solutions can be explained by flow laminarization and by the formation of internal shear-induced structures.
