an unclad optical fibre is immersed in the liquids and its optical attentuation is measured; the fibre has a refractive index greater than that of the second liquid, but not more than 01 greater than the first, and is periodically cleaned to remove any build up of the first liquid on th...
An example device may utilize the EWOD effect by providing a cylindrical glass cavity containing an electrode and dielectric layer attached to a base optical window (i.e., bottom window) with a ground electrode. The glass cavities may be filled with two immiscible liquids, where one liquid is...
(2010) to perform visualization experiments showing the invasion drainage of porous media with density-matched immiscible liquids. The second liquid phase in these tests, an organic phase consisting of a mixture of soybean oil and carbon tetrachloride, was intentionally unmatched in RI, so that it ...
However, the use of immiscible liquids causes optical disturbances due to a difference in refractive indices of the two liquids and due to a curved interface geometry. Particle images are thus imaged in a distorted field of view. The results of a PIV analysis will be inaccurate in scaling as...
The terminal droplet velocity depends on how the two liquids flow through a channel. When a droplet is much smaller than the channel cross section the resulting terminal (i.e., steady state) velocity of the droplet equals the average local velocity of the continuous phase. In general, a ...
