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…
Search and rescue at sea aided by hidden flow structures
Mattia Serra, Pratik Sathe, Irina Rypina +6
Every year hundreds of people die at sea because of vessel and airplane accidents. A key challenge in reducing the number of these fatalities is to make Search and Rescue (SAR) alg…
The Kinematics of Lagrangian Flow Separation in External Aerodynamics
Bjoern F. Klose, Mattia Serra, Gustaaf B. Jacobs
Kinematic aspects of flow separation in external aerodynamics are investigated in the Lagrangian frame. Specifically, the initial motion of upwelling fluid material from the wall i…
Material spike formation in high Reynolds number flow separation
Mattia Serra, Sean Crouzat, Gael Simon +2
We apply the recent frame-invariant theory of separation spike formation to complex unsteady flows including a turbulent separation bubble, an impinging jet, and flows around a fre…
