Capillary imbibition of monodisperse emulsions in confined microfluidic channels
Masoud Norouzi Darabad, Sagnik Singha, Jerzy Blawzdziewicz +2
We investigate imbibition of a monodisperse emulsion into a low-aspect ratio microfluidic channel with the height h comparable to the droplet diameter d. For confinement ratio d/h…
Catastrophic thermal destabilization of two-dimensional close-packed emulsions due to synchronized coalescence initiation
Samira Abedi, Chau-Chyun Chen, Siva A. Vanapalli
The mechanisms for phase separation in highly concentrated emulsions when subjected to a thermal phase transition remain to be elucidated. Here, we create a hexagonally close-packe…
Collective Nucleation Dynamics in Two-dimensional Emulsions with Hexagonal Packing
Samira Abedi, Chau-Chyun Chen, Siva A. Vanapalli
We report a new mechanism for nucleation in a monolayer of hexagonally packed monodisperse droplet arrays. Upon cooling, we observe solidified droplets to nucleate their supercoole…
Holographic shear rheology of viscoelastic fluids
Siddhartha Gupta, Siva A. Vanapalli
In this study, we report the use of digital holography microscopy (DHM) for 3D-resolved flow kinematics and shear rheometry of viscoelastic polymeric fluids. We computationally rec…
Hydrodynamic mobility of confined polymeric particles, vesicles and cancer cells in a square microchannel
Shamim M. Ahmmed, Naureen S. Suteria, Valeria Garbin +1
The transport of deformable objects including polymer particles, vesicles and cells, has been a subject of interest for several decades where the majority of experimental and theor…
Volume-of-fluid simulations in microfluidic T-junction devices: Influence of viscosity ratio on droplet size
Mehdi Nekouei, Siva A. Vanapalli
We used volume-of-fluid (VOF) method to perform three-dimensional numerical simulations of droplet formation of Newtonian fluids in microfluidic T-junction devices. To evaluate the…
