    Title: Diffusion-induced aggregation and diffusion-limited settling of particles in density-stratified fluids

    Speaker: Robert Hunt, University of Chicago

    Abstract: Many systems in nature involve fluids which are stratified by their density, the ocean being an important example. In these stratified fluids, immersed particles interact with the stratifying agent, causing both the fluid and particles to move. This talk will discuss two phenomena that arise from this coupled system: diffusion-induced aggregation, where a density field disturbance and subsequent induced flow create an effective force between particles, and diffusion-limited settling, where the rate of solute exchange between a stratified fluid and a porous particle determines the velocity at which the particle settles. In both cases, the interaction between the stratifying solute and the solid geometry plays a crucial role, and this interaction can yield emergent and counterintuitive particle behavior with relevance to carbon sequestration and ocean ecology.
