Hydrodynamics of Suspensions of Passive and Active Rigid Particles: A Rigid Multiblob Approach

3 code implementations5 Feb 2016 F. Balboa Usabiaga, B. Kallemov, B. Delmotte, A. Pal Singh Bhalla, B. E. Griffith, A. Donev

For fully confined domains, such as periodic suspensions or suspensions confined in slit and square channels, we extend a recently-developed rigid-body immersed boundary method to suspensions of freely-moving passive or active rigid particles at zero Reynolds number.

Multiscale temporal integrators for fluctuating hydrodynamics

1 code implementation1 Oct 2014 S. Delong, Y. Sun, B. E. Griffith, E. Vanden-Eijnden, A. Donev

We then include the effects of gravity, and find that we also need to include the effects of fluid inertia, which affects the dynamics of the concentration fluctuations greatly at small wavenumbers.

Brownian Dynamics without Green's Functions

2 code implementations16 Jan 2014 S. Delong, F. Balboa Usabiaga, R. Delgado-Buscalioni, B. E. Griffith, A. Donev

We develop a Fluctuating Immersed Boundary (FIB) method for performing Brownian dynamics simulations of confined particle suspensions.

Inertial Coupling Method for particles in an incompressible fluctuating fluid

1 code implementation27 Dec 2012 F. Balboa Usabiaga, R. Delgado-Buscalioni, B. E. Griffith, A. Donev

The coupling consistently includes excess (positive or negative) inertia of the particles relative to the displaced fluid, and accounts for thermal fluctuations in the fluid momentum equation.

Staggered Schemes for Fluctuating Hydrodynamics

2 code implementations25 Aug 2011 F. B. Balboa, J. B. BelL, R. Delgado-Buscalioni, A. Donev, T. G. Fai, B. E. Griffith, C. S. Peskin

We develop numerical schemes for solving the isothermal compressible and incompressible equations of fluctuating hydrodynamics on a grid with staggered momenta.
