Brownian Dynamics of Confined Suspensions of Active Microrollers
Florencio Balboa Usabiaga, Blaise Delmotte, Aleksandar Donev
We develop efficient numerical methods for performing many-body Brownian dynamics simulations of a recently-observed fingering instability in an active suspension of colloidal roll…
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…
Unstable fronts and stable "critters" formed by microrollers
Michelle Driscoll, Blaise Delmotte, Mena Youssef +3
Condensation of objects into stable clusters occurs naturally in equilibrium and driven systems. It is commonly held that potential interactions, depletion forces, or sensing are t…
Hydrodynamics of Suspensions of Passive and Active Rigid Particles: A Rigid Multiblob Approach
F. Balboa Usabiaga, B. Kallemov, B. Delmotte +3
We develop a rigid multiblob method for numerically solving the mobility problem for suspensions of passive and active rigid particles of complex shape in Stokes flow in unconfined…
