On the hydrodynamics of soap films
Web1 de jul. de 1989 · Several experiments aiming at the exploration of the hydrodynamical properties of soap films are presented. Their interpretation takes into account the very … WebThe results show that both film velocities and film flow rates increase with water sheet velocity up to a saturation level. This behavior is described via a force balance between the shear force produced by the water sheet and the opposing pulling force of reservoir and boundary layer frictions.

WebThis is the question we explore in this article by performing systematic film rupture experiments. We show that the lifetime and maximal length of the films are fairly reproducible and controlled only by hydrodynamics. For surfactants with high surface elastic modulus, we argue that the rupture is triggered by the expansion of a thinning … WebIN a recent communication 1, I suggested that the Gibbs theory of surface elasticity provided a satisfactory interpretation of the experimental elasticities of films of sodium dodecyl sulphate...
