Particle suspensions are ubiquitous in nature and technology. Among the numerous phenomena in geology and geophysics, suspension behavior is important to understand avalanches and debris flows. They are important to understand the rheology of crystal rich magmas, as well as transport of subsurface contaminants. In industry, suspensions are part of paper coatings, paints, and foodstuffs, and are also used in extraction processes of natural gas. Suspensions in biology include the flow of blood, as well as swimming bacteria, which is an example from the broader definition of active matter.
Despite the large number of applications, many aspects of suspension behavior remain elusive. This thesis explores the statistical properties of suspensions in shear flow, including self diffusion, particle clustering and effective viscosity.
