- Effects of rheological properties of the fluids on migration behavior of double emulsions
抄録
<p>Particle migration in microfluidic devices has received considerable attention because of its applications in medicine, chemistry, and engineering, including diagnostics, particle separation, and cell sorting. In this study, we observe inertial migration of soft particles in a straight tube at Re ranging from 100 to 1000. Uniform double emulsions as soft particles are produced by a flow focusing technique in a micro fluidic device. Mechanical properties of the double emulsions were measured prior to migration experiments. Equilibrium radial positions of the double emulsions were measured at several Re. Re affected the distance from the tube center and numbers of the equilibrium radial position. In Re < 250 range, a single equilibrium radial position was observed, which gradually shifted toward the channel wall. Two equilibrium positions were observed at Re ranging from 300 to 500. In Re > 500 range, a single equilibrium radial position closer to the center was observed. These different flow regimes and transitions were influenced by particle deformability.</p>
