Approximate streamsurfaces for flow visualization
Stergios Katsanoulis, Florian Kogelbauer, Roshan Kaundinya +2
Instantaneous features of three-dimensional velocity fields are most directly visualized via streamsurfaces. It is generally unclear, however, which streamsurfaces one should pick…
Objective barriers to the transport of dynamically active vector fields
George Haller, Stergios Katsanoulis, Markus Holzner +2
We derive a theory for material surfaces that maximally inhibit the diffusive transport of a dynamically active vector field, such as the linear momentum, the angular momentum or t…
Vortex boundaries as barriers to diffusive vorticity transport in two-dimensional flows
Stergios Katsanoulis, Mohammad Farazmand, Mattia Serra +1
We put forward the idea of defining vortex boundaries in planar flows as closed material barriers to the diffusive transport of vorticity. Such diffusive vortex boundaries minimize…
