Axial dispersion in dilute solutions of linear and branched polymers in parallel-plate and expansion-contraction microchannels
C. Levi Petix, Tzortzis Koulaxizis, Griffin D. Overton +2
The axial dispersion of polymers in microchannels depends on an interplay between microchannel geometry, polymer architecture, and hydrodynamics. Here, we investigate the axial dis…

Effect of Pre-Shear and Dispersity on Crystallization of a Model Polymer with Soft Pair Interactions using Molecular Dynamics Simulations
Tzortzis Koulaxizis, Antonia Statt
Polymer crystallization is a process of great interest in both fundamental theory and industrial settings, particularly in polymer processing and applications involving semi-crysta…

Mesoscale particle-based simulations of flow in expansion-contraction microchannels at low Reynolds number
Tzortzis Koulaxizis, Clara De La Torre Garcia, C. Levi Petix +2
We computationally study the flow of Newtonian fluids through sinusoidal expansion-contraction microchannels at low Reynolds number. We first use a perturbation method to analytica…
