Defect-mediated dynamics of coherent structures in active nematics
Mattia Serra, Linnea Lemma, Luca Giomi +2
Active fluids, such as cytoskeletal filaments, bacterial colonies and epithelial cell layers, exhibit distinctive orientational coherence, often characterized by nematic order and…
Objective early identification of kinematic instabilities in shear flows
Bjoern F. Klose, Mattia Serra, Gustaaf B. Jacobs
A kinematic approach for the identification of flow instabilities is proposed. By defining a flow instability in the Lagrangian frame as the increased folding of lines of fluid par…
Optimal policies for mitigating pandemic costs
M. Serra, S. al-Mosleh, S. Ganga Prasath +5
Several non-pharmaceutical interventions have been proposed to control the spread of the COVID-19 pandemic. On the large scale, these empirical solutions, often associated with ext…
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…
