Droplet-String Deformation and Stability during Microconfined Shear Flow

  title={Droplet-String Deformation and Stability during Microconfined Shear Flow},
  author={Jai A. Pathak and Kalman B. Migler},
We have performed experiments on model emulsions of polyisobutylene (PIB) and poly(dimethylsiloxane) (PDMS) to quantify the effect of confinement on deformation and stability under flow of droplets and strings (threads). It is known from earlier work from our group that, under confinement, droplets in concentrated emulsions can coalesce with each other and elongate in the flow direction to form stable strings. In the present context, strings can be simply viewed as droplets having a large… CONTINUE READING
