From Hindered to Promoted Settling in Dispersions of Attractive Colloids: Simulation, Modeling, and Application to Macromolecular Characterization
Andrew M. Fiore, Gang Wang, James W. Swan
The settling of colloidal particles with short-ranged attractions is investigated via highly resolved immersed boundary simulations. At modest volume fractions, we show that inter-…
Rapid Sampling of Stochastic Displacements in Brownian Dynamics Simulations with Stresslet Constraints
Andrew M. Fiore, James W. Swan
Brownian Dynamics simulations are an important tool for modeling the dynamics of soft matter. However, accurate and rapid computations of the hydrodynamic interactions between susp…
How Confinement-Induced Structures Alter the Contribution of Hydrodynamic and Short-Ranged Repulsion Forces to the Viscosity of Colloidal Suspensions
Meera Ramaswamy, Neil Y. C. Lin, Brian D. Leahy +4
Understanding the correlation between structure and rheology in colloidal suspensions is important as these suspensions are crucial in industrial applications. Moreover, colloids e…
Rapid Sampling of Stochastic Displacements in Brownian Dynamics Simulations
A. M. Fiore, F. Balboa Usabiaga, A. Donev +1
We present a new method for sampling stochastic displacements in Brownian Dynamics (BD) simulations of colloidal scale particles. The method relies on a new formulation for Ewald s…
