Web26 de abr. de 2006 · The mean film thickness, prior to rupture, was measured by an electrical conductivity method: initial film thicknesses were of order 0.3–0.9 μm. For an unruptured film, drainage due to gravity reduced the film thickness; the films ruptured naturally at a thickness of order 0.05–0.09 μm. WebHowever, Prof. K. J. Mysels 3 has kindly pointed out that my equation 3 implies depletion of the surface-active solute by adsorption while the soap film is being formed, whereas, in … Webwhen a horizontal soap ﬁlm was submitted to a monochromatic acoustic wave [13]. Many studies have attempted to rationalize these phenomena [10, 14–18]. The underlying physics resides in the hydrodynamics of the liquid and the surrounding air, and the way those ﬂows are coupled at the liquid interfaces of the thin ﬁlm.
