Large Scale Simulations of Brownian Suspensions
Our algorithm follows a Stokesian dynamics formulation by evaluating many-body hydrodynamic interactions using a far-field multipole expansion combined with a near-field lubrication correction. The breakthrough O(N ln N) scaling is obtained by employing a Particle-Mesh-Ewald (PME) approach whereby …

Large Scale Simulations of Particulate Systems Using the PME Method
… demonstrating its accuracy and speed relative to Stokesian dynamics and spectral boundary integral computations. The speed of the algorithm is such that simulations of 4096 particles may be run on an IBM RS6000 workstation. Memory requirements are modest, and extension of the method to …

Mechanics of polydisperse suspensions
… e.g. particles of different density. Using the stokesian dynamics algorithm, mobility matrices are computed for random particle configurations and ensemble averages taken to calculate the mean mobility matrices. It is shown that the settling velocities of individual particle species may be …

Hydrodynamic Simulations of Colloidal Gels: Microstructure, Dynamics, and Rheology
The microstructure, dynamics, and rheology of colloidal suspensions with short-range depletion attraction and long-range electrostatic repulsion are studied using equilibrium predictions and a new algorithm for dynamic simulations. A focus is made on those combinations of attraction and repulsion …

Dynamic simulations of particle suspensions subjected to an external electric-field
… acting on the particles is determined using the Stokesian dynamics method under the assumption that the Reynolds number is much smaller than 1, while the electrostatic force is determined by differentiating the electrostatic energy of the suspension, which is computed from the induced particle …

Transport properties of graphite-loaded composites in liquid and solid states
… the experimental data using ideas from Stokesian dynamics simulations and combined with understandings of the internal structures of suspensions. Our studies show although Brownian motion is not important for thermal transport, it is important for rheological properties of the …

Collective behavior of colloidal suspensions under electric fields and confinement
… area of interest in the present study, particle dynamics driven by electrokinetic phenomena in Stokes flow are investigated using theory and numerical simulations. In particular, we focus on the dynamics and collective behavior of colloidal suspensions of spherical particles under electric fields …

Efficient coarse-grained brownian dynamics simulations for dna and lipid bilayer membrane with hydrodynamic interactions
The coarse-grained molecular dynamics (CGMD) or Brownian dynamics (BD) simulation is a particle-based approach that has been applied to a wide range of biological problems that involve interactions with surrounding fluid molecules or the so-called hydrodynamic interactions (HIs). From simple …
