Universality of stretching separation

  title={Universality of stretching separation},
  author={David Baumgartner and G{\"u}nter Brenn and Carole Planchette},
We develop a parameter-free model for the fragmentation of drops colliding off-center. The prediction is excellent over a wide range of liquid properties. The so-called stretching separation is attributed to the extension of the merged drop above a critical aspect ratio of 3.25. The evolution of this aspect ratio is influenced by the liquid viscosity and can be interpreted via an energy balance. This approach is then adapted to drop-jet collisions, which we model as consecutive drop-drop… 


Colliding drops as coalescing and fragmenting liquid springs
A universal modelling approach of drop fragmentation after head-on drop collisions is presented. In this approach, the colliding drops are seen as liquid springs that coalesce, compress and relax,
Coalescence and separation in binary collisions of liquid drops
An extensive experimental investigation of the binary collision dynamics of water drops for size ratios of 1. 0.75, and 0.5, for the Weber-number range of 1 to 100, and for all impact parameters is
Inertial stretching separation in binary droplet collisions
Abstract Binary droplet collisions exhibit a wide range of outcomes, including coalescence and stretching separation, with a transition between these two outcomes arising for high Weber numbers and
Inertia dominated drop collisions. I. On the universal flow in the lamella
This study is devoted to the analysis of inertia dominated axisymmetric drop collisions with a dry substrate or with another liquid drop. All the previous theoretical and semiempirical models of drop
Separation Criteria for Off-Axis Binary Drop Collisions
Off-axis collisions of two equal size droplets are investigated numerically. Various governing processes in such collisions are discussed. Several commonly used theoretical models that predict the
Influence of liquid miscibility and wettability on the structures produced by drop–jet collisions
Collisions between a stream of drops and a continuous jet of a different liquid are experimentally investigated. In contrast to previous studies, our work focuses on the effects of liquid miscibility
Collisions of a string of water drops on a water jet of equal diameter
The collision between a water drop and a water jet of equal diameter was experimentally studied. The collision outcome was found to depend on the impact parameter, the cross-jet Weber number, and the

In this Letter, coalescence-bouncing transitions of head-on binary droplet collisions are predicted by a novel macroscopic model based entirely on fundamental laws of physics and modified the Navier-Stokes equations to accurately account for the rarefied nature of the interdroplet gas film.
Simulation of binary droplet collisions with the entropic lattice Boltzmann method
The recently introduced entropic lattice Boltzmann method (ELBM) for multiphase flows is extended here to simulation of droplet collisions. Thermodynamically consistent, non-linearly stable ELBM
Satellite droplet formation by unstable binary drop collisions
The formation of satellite droplets by stretching separation in unstable binary collisions of equal-sized drops is investigated. Based on data from detailed experiments on the formation and breakup
