### Non-spherical Particles in Fluids

Fluid flows containing rigid particles appear in many applications. While
spherical particles in fluids is a well-studied area, the assumption that
particles are spheres is almost never realistic in applications. To discretise
this coupled fluid-rigid body problem while being flexible with respect to the
geometry of the resulting fluid domain, we use unfitted finite element methods.

The complexity of this problem is very large and dependent on factors such as
the size and number of particles, contact between particles resulting in
topology changes, as well as interaction between the particles and the
surrounding fluid. With a decrease in the size of the particles and an increase
of the number of particles, fully resolved direct numerical simulations will
become infeasible. It is therefore necessary to develop new methods which reduce
the complexity of this problem sufficiently for efficient computability.
However, these methods must also deal with contact between particles, as well as
the interaction between the particles and the surrounding fluid with sufficient
accuracy.
