The Two Fluid Drop Snap-off Problem : Experiments and Theory

  title={The Two Fluid Drop Snap-off Problem : Experiments and Theory},
  author={Itai Cohen and Michael P. Brenner and Jens Eggers and Sidney R. Nagel},
We address the dynamics of a drop with viscosity λη breaking up inside another fluid of viscosity η. For λ = 1, a scaling theory predicts the time evolution of the drop shape near the point of snap-off which is in excellent agreement with experiment and previous simulations of Lister and Stone. We also investigate the λ dependence of the shape and breaking rate. When a fluid droplet breaks, as shown in Figure 1, a singularity develops due to the infinite curvature at the point of snap-off [1… CONTINUE READING
