Experimental observation of local rearrangements in dense quasi-two-dimensional emulsion flow.
We experimentally study rearranging regions in slow athermal flow by observing the flow of a concentrated oil-in-water emulsion in a thin chamber with a constricting hopper shape. The gap of the chamber is smaller than the droplet diameters, so that the droplets are compressed into quasi-two-dimensional pancakes. We focus on localized rearrangements known as "T1 events" where four droplets exch...
متن کاملTopological rearrangements and stress fluctuations in quasi-two-dimensional hopper flow of emulsions
We experimentally study the shear flow of oil-in-water emulsion droplets in a thin sample chamber with a hopper shape. In this thin chamber, the droplets are quasi-2D in shape. The sample is at an area fraction above jamming and forced to flow with a constant flux rate. Stresses applied to a droplet from its neighbors deform the droplet outline, and this deformation is quantified to provide an ...
متن کاملExperimental study of forces between quasi - two - dimensional emulsion droplets near jamming
We experimentally study the jamming of quasi-two-dimensional emulsions. Our experiments consist of oilin-water emulsion droplets confined between two parallel plates. From the droplet outlines, we can determine the forces between every droplet over a wide range of area fractions f. We study three bidisperse samples that jam at area fractions fc z 0.86. Our data show that for f > fc, the contact...
متن کاملParametric Study of Movement Path in Two-dimensional Wing Flow Separation: Experimental Investigation
The aim of this experimental study is two-dimensional investigation of cargo behavior after separation which is carried out in the subsonic wind tunnel. Given that the real separation occurs in three-dimension, the results of this study may be widely used in numerical aerodynamic studies for verification of new computational methods and they can be used as the reference results in this area. So...
متن کاملModification of flow and compressibility of corn starch using quasi-emulsion solvent diffusion method
Objective(s):The aim of this study was to improve flowability and compressibility characteristics of starch to use as a suitable excipient in direct compression tabletting. Quasi-emulsion solvent diffusion was used as a crystal modification method. Materials and Methods: Corn starch was dissolved in hydrochloric acid at 80˚C and then ethanol as a non-solvent was added with lowering temperature ...
