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…
Approximation of forces and torques from anisotropic pairwise interactions using multivariate polynomials
Mohammadreza Fakhraei, Michaela Bush, Chris A. Kieslich +1
The dynamics of anisotropic particles are dictated by forces and torques that can be challenging to mathematically represent in computer simulations. Several data-driven approaches…
Effects of skewing collision cells on transport properties in multiparticle collision dynamics simulations
Jinny Cha, Wilfred Kwabena Darko, Jeremy C. Palmer +1
Multiparticle collision dynamics (MPCD) is a mesoscale simulation technique that uses a simplified solvent to model hydrodynamic interactions. Rather than interact through pairwise…
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…
Designing binary mixtures of colloidal particles with simple interactions that assemble complex crystals
Beth Hsiao-Yen Wei, C. Levi Petix, Qizan Chen +2
Computational methods for designing interactions between colloidal particles that induce self-assembly have received much attention for their promise to discover tailored materials…
