Abstract: Turbulent fluids laden with small, heavy particles are common in nature. Prominent examples of such turbulent suspensions are water droplets in warm clouds, as well as particulate matter or living organisms in the turbulent upper layer of oceans. Because of their inertia, heavy particles tend to distribute inhomogeneously over phase-space, and over configuration space. This phenomenon is referred to as clustering, and it is believed to have a strong impact on the rate of collisions between parti... more
