• STABILITY ANALYSIS OF EVAPORATING THIN LIQUID FILMS IN THE PRESENCE OF SURFACTANT

Hajar Farhan Ismael*

Abstract


This research is dedicated for analyzing the stability of thin liquid film in the presence of heat and surfactant, the fluid flow of thin liquid films represents by Navier-Stokes equation and equation of continuity in two dimensional forms as shown in figure (1). We find that the stability of films occur when the Prandtl and Schmidt numbersare greater than zero,otherwise the film become unstable.
