Breakup Dynamics of Droplets in Symmetric Y-Junction Microchannels

Polymer drop breakup in microchannels.

Droplet Breakup in Expansion-contraction Microchannels

We investigate the influences of expansion-contraction microchannels on droplet breakup in capillary microfluidic devices. With variations in channel dimension, local shear stresses at the injection nozzle and focusing orifice vary, significantly impacting flow behavior including droplet breakup locations and breakup modes. We observe transition of droplet breakup location from focusing orifice...

Polymeric filament thinning and breakup in microchannels.

The effects of elasticity on filament thinning and breakup are investigated in microchannel cross flow. When a viscous solution is stretched by an external immiscible fluid, a low 100 ppm polymer concentration strongly affects the breakup process, compared to the Newtonian case. Qualitatively, polymeric filaments show much slower evolution, and their morphology features multiple connected drops...

Y-Junction based addressing in Optical Symmetric Multiprocessor Networks

1. Introduction In a symmetric multiprocessor (SMP), every processor has its own cache, and all the processors and memory modules are connected to the central interconnect, which is usually a shared bus. As the processors become faster, the central interconnect architecture of traditional SMP's impedes performance because it cannot keep up with the processors capabilities. As SMP's have hardwar...

Deformation and breakup of high-viscosity droplets with symmetric microfluidic cross flows.

The dynamic response of highly viscous droplets to a sharp increase in the surrounding liquid velocity is experimentally investigated in a square microchannel junction. The local injection of the continuous phase from symmetric side channels onto a train of droplets produces a large velocity contrast between the front and the rear of droplets, yielding a broad range of time-dependent deformatio...
