Concentration Matters: Enhancing Particle Settling in Narrow Tilted Channels
Dipankar Kundu, Florencio Balboa Usabiaga, Adolfo Vázquez-Quesada +1
Particles are known to sediment faster in containers with tilted walls than in vertical ones, a phenomenon known as the Boycott effect. In this work, we investigate how the tilt an…
Simulating non-Brownian suspensions with non-homogeneous Navier slip boundary conditions
Daniela Moreno-Chaparro, Florencio Balboa Usabiaga, Nicolas Moreno +1
Fluid-structure interactions are commonly modeled using no-slip boundary conditions. However, small deviations from these conditions can significantly alter the dynamics of suspens…
Modeling complex particle suspensions: perspectives on the rigid multiblob method
Blaise Delmotte, Florencio Balboa Usabiaga
Many suspensions contain particles with complex shapes that are affected not only by hydrodynamics, but also by thermal fluctuations, internal kinematic constraints and other long-…
Settling dynamics of non-Brownian suspension of spherical and cubic particles in Stokes flow
Dipankar Kundu, Florencio Balboa Usabiaga, Marco Ellero
The present study investigates the gravity-driven settling dynamics of non-Brownian suspensions of spherical and cubic particles within a triply periodic domain. The effect of soli…
A scalable method to model large suspensions of colloidal phoretic particles with arbitrary shapes
Blaise Delmotte, Florencio Balboa Usabiaga
Phoretic colloids self-propel thanks to surface flows generated in response to surface gradients (thermal, electrical, or chemical), that are self-induced and/or generated by other…
Mapping flagellated swimmers to surface-slip driven swimmers
H. Gidituri, G. Kabacaoğlu, M. Ellero +1
Flagellated microswimmers are ubiquitous in natural habitats. Understanding the hydrodynamic behavior of these cells is of paramount interest, owing to their applications in bio-me…
Computational modelling of passive transport of functionalized nanoparticles
Daniela Moreno-Chaparro, Nicolas Moreno, Florencio Balboa-Usabiaga +1
Functionalized nanoparticles (NPs) are complex objects present in a variety of systems ranging from synthetic grafted nanoparticles to viruses. The morphology and number of the dec…
A numerical method for suspensions of articulated bodies in viscous flows
Florencio Balboa Usabiaga, Blaise Delmotte
An articulated body is defined as a finite number of rigid bodies connected by a set of arbitrary constraints that limit the relative motion between pairs of bodies. Such a general…
Metallic Microswimmers Driven up the Wall by Gravity
Quentin Brosseau, Florencio Balboa Usabiaga, Enkeleida Lushi +5
As a natural and functional behavior, various microorganisms exhibit gravitaxis by orienting and swimming upwards against gravity. Swimming autophoretic nanomotors described herein…
Relating microswimmer synthesis to rheotactic tunability
Quentin Brosseau, Florencio Balboa Usabiaga, Enkeleida Lushi +5
We explore the behavior of micron-scale autophoretic Janus (Au/Pt) rods, having various Au/Pt length ratios, swimming near a wall in an imposed background flow. We find that their…
Hydrodynamic fluctuations in quasi-two dimensional diffusion
R. P. Peláez, F. Balboa Usabiaga, S. Panzuela +3
We study diffusion of colloids on a fluid-fluid interface using particle simulations and fluctuating hydrodynamics. Diffusion on a two-dimensional interface with three-dimensional…

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…
