Francesca Bernardi, Ph.D. Candidate Department of Mathematics University of North Carolina at Chapel Hill Symmetry-breaking in passive scalars advected by laminar shear flow Abstract: The dispersion of passive tracers in laminar shear flow is a classic problem in fluid dynamics. The boost in the tracer dispersion due to the interplay between advection and diffusion was first described mathematically and observed experimentally by Sir G. I. Taylor in 1953 for laminar flow in a straight circular pipe.
