Barriers to the Transport of Diffusive Scalars in Compressible Flows
George Haller, Daniel Karrasch, Florian Kogelbauer
Our recent work identifies material surfaces in incompressible flows that extremize the transport of an arbitrary, weakly diffusive scalar field relative to neighboring surfaces. S…

Material Barriers to Diffusive and Stochastic Transport
George Haller, Daniel Karrasch, Florian Kogelbauer
We seek transport barriers and transport enhancers as material surfaces across which the transport of diffusive tracers is minimal or maximal in a general, unsteady flow. We find t…
