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…
Enhanced flow rate by the concentration mechanism of Tetris particles when discharged from a hopper with an obstacle
Guo-Jie Jason Gao, Fu-Ling Yang, Michael C. Holcomb +1
We apply a holistic 2D Tetris-like model, where particles move based on prescribed rules, to investigate the flow rate enhancement from a hopper. This phenomenon was originally rep…
Understanding the Local Flow Rate Peak of a Hopper Discharging Discs through an Obstacle Using a Tetris-like Model
Guo-Jie J. Gao, Jerzy Blawzdziewicz, Michael C. Holcomb +1
Placing a round obstacle above the orifice of a flat hopper discharging uniform frictional discs has been experimentally and numerically shown in the literature to create a local p…
Maximum likelihood estimations of force and mobility from short single Brownian trajectories
Raphael Sarfati, Jerzy Blawzdziewicz, Eric R. Dufresne
We describe a method to extract force and diffusion parameters from single trajectories of Brownian particles based on the principle of maximum likelihood. The analysis is well-sui…
Embryo as an active granular fluid: stress-coordinated cellular constriction chains
Guo-Jie Jason Gao, Michael C. Holcomb, Jeffrey H. Thomas +1
Mechanical stress plays an intricate role in gene expression in individual cells and sculpting of developing tissues. However, systematic methods of studying how mechanical stress…
Near-Wall Dynamics of Concentrated Hard-Sphere Suspensions: Comparison of Evanescent Wave DLS Experiments, Virial Approximation and Simulations
Yi Liu, Jerzy Blawzdziewicz, Bogdan Cichocki +5
In this article we report on a study of the near-wall dynamics of suspended colloidal hard spheres over a broad range of volume fractions. We present a thorough comparison of exper…
