Coherent structure colouring: identification of coherent structures from sparse data using graph theory [PDF]
Journal of Fluid Mechanics, 2016 We present a frame-invariant method for detecting coherent structures from Lagrangian flow trajectories that can be sparse in number, as is the case in many fluid mechanics applications of practical interest. The method, based on principles used in graph

Dynamics of large-scale structures and heat transfer in turbulent mixed convection [PDF]
, 2009 Low frequency oscillations have been observed in the heat transfer of mixed convection in a rectangular cavity with an aspect ratio of $\Gamma_{\mathrm{xz}} = 1$ and $\Gamma_{\mathrm{yz}} = 5$.~Mixed convective flow at $Ra = 2.4 \times 10^8$, $Re = 1.0 ...

Perverse coherent t-structures through torsion theories [PDF]
, 2014 Bezrukavnikov, later together with Arinkin, recovered Deligne’s work defining perverse t-structures in the derived category of coherent sheaves on a projective scheme.

Reduced Models of Point Vortex Systems
Entropy, 2018 Nonequilibrium statistical models of point vortex systems are constructed using an optimal closure method, and these models are employed to approximate the relaxation toward equilibrium of systems governed by the two-dimensional Euler equations, as well ...

Inventions, 2023 Backward-facing steps are commonly formed on wings and blades due to misalignment between segments or the addition of protective films. A backward-facing step (BFS) is known to degrade the airfoil performance.

TRPIV measurement of turbulent coherent structures in a drag-reducing flow by polymers
, 2013 Fully developed turbulent flow fields with and without polymer solution at the same Reynolds number were measured by time-resolved particle image velocimetry (TRPIV) in a water channel to investigate the mechanism of drag-reducing solution from the view ...

Antisymmetric quadrupole mode of coherent structures in wall-bounded turbulence
, 2013 Experiments were conducted in a water tunnel by tomographic time-resolved particle image velocimetry (Tomo-TRPIV). The Reynolds number Reθ is 2460 on the base of momentum thickness.

The Intermittency of Turbulence in Magneto-Hydodynamical Simulations and in the Cosmos
AtmosphereTurbulent dissipation is a central issue in the star and galaxy formation process. Its fundamental property of space–time intermittency, well characterised in incompressible laboratory experiments, remains elusive in cosmic turbulence.

The emergence of a coherent structure for coherent structures: localized states in nonlinear systems [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2010 Coherent structures emerge from the dynamics of many kinds of dissipative, externally driven, nonlinear systems, and continue to provoke new questions that challenge our physical and mathematical understanding. In one specific subclass of such problems, in which a pattern-forming, or ‘Turing’, instability occurs, rapid progress has been made recently ...
