Dynamics of acoustically levitated drops with Ouzo effect
نویسندگان
چکیده
Ouzo effect represents a typical spontaneous emulsification process, which is widely used in many fields such as chemical industry, biomedicine and fabrication of novel materials. This work attempts to clarify the influence sound field container-free conditions on by combining transition with action field. We compare dynamic process performing experiments glass slide an acoustic levitator, respectively, through triggering via evaporation droplet coalescence. observe evaporation-induced transition, growth emerged oil satisfies Fick’s law suggesting dominated diffusion. Under levitation, driven produces small droplets divinylbenzene that rapidly diffuse convection distribute uniformly throughout until only continuous remains. Droplet coalescence could result lead abnormal shape levitated drop, contains micron-sized under levitation. By decreasing intensity field, returns axisymmetrical then recovers its initial upon enhancing intensity, indicating flow plays important role maintaining irregular droplet. The caused both internal flows radiation pressure exerted drop surface. study may shed light developing new techniques for micro-emulsification related

Generation and characterization of surface layers on acoustically levitated drops.
Surface layers of natural and technical amphiphiles, e.g., octadecanol, stearic acid and related compounds as well as perfluorinated fatty alcohols (PFA), have been investigated on the surface of acoustically levitated drops. In contrast to Langmuir troughs, traditionally used in the research of surface layers at the air-water interface, acoustic levitation offers the advantages of a minimized ...
متن کاملChemical analysis of acoustically levitated drops by Raman spectroscopy
An experimental apparatus combining Raman spectroscopy with acoustic levitation, Raman acoustic levitation spectroscopy (RALS), is investigated in the field of physical and chemical analytics. Whereas acoustic levitation enables the contactless handling of microsized samples, Raman spectroscopy offers the advantage of a noninvasive method without complex sample preparation. After carrying out s...
متن کاملOscillating and star-shaped drops levitated by an airflow.
We investigate the spontaneous oscillations of drops levitated above an air cushion, eventually inducing a breaking of axisymmetry and the appearance of "star drops". This is strongly reminiscent of the Leidenfrost stars that are observed for drops floating above a hot substrate. The key advantage of this work is that we inject the airflow at a constant rate below the drop, thus eliminating the...
