Large cells often rely on cytoplasmic flows for intracellular transport, maintaining
homeostasis, and positioning cellular components. Understanding the mechanisms of these …

The interaction of fibers in a viscous (Stokes) fluid plays a crucial role in industrial and
biological processes, such as sedimentation, rheology, transport, cell division, and …

We describe a computational framework for simulating suspensions of rigid particles in
Newtonian Stokes flow. One central building block is a collision-resolution algorithm that …

We perform detailed computational and experimental measurements of the driven dynamics
of a dense, uniform suspension of sedimented microrollers driven by a magnetic field …

A method is presented for calculating Stokes flow around multiple particles of arbitrary
shape. It uses the Method of Fundamental Solutions (MFS) applied to single particles …

This paper describes a novel partitioned algorithm for fluid–structure interaction (FSI)
problems that couples the motion of rigid bodies and incompressible flow. This is the first …

Stokes flows with near-touching rigid particles induce near-singular lubrication forces under
relative motion, making their accurate numerical treatment challenging. With the aim of …

We show that the standard boundary integral operators, defined on the unit sphere, for the
Stokes equations diagonalize on a specific set of vector spherical harmonics and provide …

In this work, we provide a solution to the problem of computing collision stress in particle-
tracking simulations. First, a formulation for the collision stress between particles is derived …

We develop numerical methods to simulate the fluid-mechanical erosion of many bodies in
two-dimensional Stokes flow. The broad aim is to simulate the erosion of a porous medium …
