Accurate lubrication corrections for spherical and non-spherical particles in discretized fluid simulations [PDF]
, 2013 Discretized fluid solvers coupled to a Newtonian dynamics method are a popular tool to study suspension flow. As any simulation technique with finite resolution, the lattice Boltzmann method, when coupled to discrete particles using the momentum exchange

Stochastic multiscale analysis in hydrodynamic lubrication [PDF]
International Journal for Numerical Methods in Engineering, 2017 SummaryA stochastic multiscale analysis framework is developed for hydrodynamic lubrication problems with random surface roughness. The approach is based on a multi‐resolution computational strategy wherein the deterministic solution of the multiscale problem for each random surface realization is achieved through a coarse‐scale analysis with a local ...

Trajectory analysis for non-Brownian inertial suspensions in simple shear flow [PDF]
, 2006 We analyse pair trajectories of equal-sized spherical particles in simple shear flow for small but finite Stokes numbers. The Stokes number, $\mbox{\textit{St}} \,{=}\, \dot{\gamma} \tau_p$, is a dimensionless measure of particle inertia; here, $\tau_p ...

Simulating (electro)hydrodynamic effects in colloidal dispersions: smoothed profile method
, 2008 Previously, we have proposed a direct simulation scheme for colloidal dispersions in a Newtonian solvent [Phys.Rev.E 71,036707 (2005)]. An improved formulation called the ``Smoothed Profile (SP) method'' is presented here in which simultaneous time ...
