abstract = {<p style="text-align: justify;">We study the settling of solid particles in a viscous incompressible fluid contained
within a two-dimensional channel, where the mass density of the particles is
greater than that of the fluid. The fluid-structure interaction problem is simulated
numerically using the immersed boundary method, where the added mass is incorporated
using a Boussinesq approximation. Simulations are performed with a single
circular particle, and also with two particles in various initial configurations. The terminal
particle settling velocity and drag coefficient correspond closely with other theoretical,
experimental and numerical results, and the particle trajectories reproduce
the expected behavior qualitatively. In particular, simulations of a pair of interacting
particles similar drafting-kissing-tumbling dynamics to that observed in other experimental
and numerical studies.</p>},
