Dynamics of a droplet in shear flow by smoothed particle hydrodynamics
Frontiers in Physics, 2023 The behavior of a droplet under shear flow in a confined channel is studied numerically using a multi-phase smoothed particle hydrodynamics (SPH) method.

Droplet Growth and Transition to Coalescence in Confined Geometries [PDF]
Langmuir, 2006 A thermodynamic theory is developed to predict growth, rearrangement to a close-packed ensemble, and transition to a deformed or coalesced state for droplets in a confined space. For the close-packed configuration, analysis of forced interactions between confined droplets yields analytical criteria for predicting whether droplets will deform and if ...

Droplet Dynamics of Newtonian and Inelastic Non-Newtonian Fluids in Confinement
Micromachines, 2017 Microfluidic droplet technology has been developing rapidly. However, precise control of dynamical behaviour of droplets remains a major hurdle for new designs.

Immersed Boundary Simulations of Active Fluid Droplets. [PDF]
PLoS ONE, 2016 We present numerical simulations of active fluid droplets immersed in an external fluid in 2-dimensions using an Immersed Boundary method to simulate the fluid droplet interface as a Lagrangian mesh.

Self-bound crystals of antiparallel dipolar mixtures
Physical Review Research, 2023 Recent experiments have created supersolids of dipolar quantum droplets. The resulting crystals lack, however, a genuine cohesive energy and are maintained by the presence of an external confinement, bearing a resemblance to the case of ion Coulomb ...

Coalescence and splitting of confined droplets at microfluidic junctions [PDF]
Lab on a Chip, 2009 The ability to merge two droplets is an important component of droplet-based lab-on-a-chip devices, yet flow-induced coalescence is difficult to achieve due to long film drainage times compared with relatively short residence times. We examine droplet collisions at a simple microfluidic T-junction and characterize the response for a wide range of ...

Rotating quantum droplets confined in an anharmonic potential
Physical Review A, 2023 We investigate the rotational properties of quantum droplets, which form in a mixture of two Bose-Einstein condensates, in the presence of an anharmonic trapping potential. We identify various phases as the atom number and the angular momentum or angular velocity of the trap vary.

Confined and colloidal droplets [PDF]
, 2020 The evaporation of confined and colloidal droplets has been examined in different configurations and systems. The confinement is achieved by fully immersing the droplet in an elastic medium. When the droplet evaporates, it also deforms the surrounding elastic gel.

Self-Similar Relaxation of Confined Microfluidic Droplets [PDF]
Physical Review Letters, 2019 We report an experimental study concerning the capillary relaxation of a confined liquid droplet in a microscopic channel with a rectangular cross section. The confinement leads to a droplet that is extended along the direction normal to the cross section.
