Mitigation of tipping point transitions by time-delay feedback control
Mohammad Farazmand
In stochastic multistable systems driven by the gradient of a potential, transitions between equilibria is possible because of noise. We study the ability of linear delay feedback…
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…
Closed-loop adaptive control of extreme events in a turbulent flow
Mohammad Farazmand, Themistoklis P. Sapsis
Extreme events that arise spontaneously in chaotic dynamical systems often have an adverse impact on the system or the surrounding environment. As such, their mitigation is highly…
Surface waves enhance particle dispersion
Mohammad Farazmand, Themistoklis Sapsis
We study the horizontal dispersion of passive tracer particles on the free surface of gravity waves in deep water. For random linear waves with the JONSWAP spectrum, the Lagrangian…
Are extreme dissipation events predictable in turbulent fluid flows?
Patrick J. Blonigan, Mohammad Farazmand, Themistoklis P. Sapsis
We derive precursors of extreme dissipation events in a turbulent channel flow. Using a recently developed method that combines dynamics and statistics for the underlying attractor…
Variational Lagrangian formulation of the Euler equations for incompressible flow: A simple derivation
Mohammad Farazmand, Mattia Serra
In 1966, Arnold [1] showed that the Lagrangian flow of ideal incompressible fluids (described by Euler equations) coincide with the geodesic flow on the manifold of volume preservi…
