On the hydrodynamics of soap films
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. Figure 2.

Web10 de abr. de 2024 · ABSTRACT. We apply a coarse-graining technique to understand the efficiency of scale-to-scale transport of energy and enstrophy in a quasi-two-dimensional weakly turbulent periodic flow. The investigated periodic flow resembles the propagation of a monochromatic tide in a tidal channel, connected to open sea through an inlet. Web26 de mar. de 2014 · The hydrodynamics of thin films is an important factor when it comes to the stability and rheology of multiphasic materials, such as foams, emulsions, and …
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. Web1 de nov. de 2024 · In this short review, I focus on recent experiments that benefit from the advantages offered by the two-dimensionality of the flow in suspended thin liquid films to reconsider hydrodynamics problems which have resisted a full understanding.
