### Helicity and singular structures in fluid dynamics

- PhysicsProceedings of the National Academy of Sciences

Issues of the dynamics of fluids that are of central importance for (i) the origin of planetary and astrophysical magnetism, and (ii) the determination of stable magnetic field configurations used in thermonuclear fusion reactors like the tokamak are covered.

### Flight–crash events in turbulence

- PhysicsProceedings of the National Academy of Sciences
- 2014

It is shown that the motion of a single fluid particle provides a clear manifestation of time irreversibility, and finds that the third moment of the power fluctuations along a trajectory, nondimensionalized by the energy flux, displays a remarkable power law as a function of the Reynolds number.

Dynamo action is demonstrated numerically in the forced Taylor–Green (TG) vortex made up of a confined swirling flow composed of a shear layer between two counter-rotating eddies, corresponding to a…

### Conservation of writhe helicity under anti-parallel reconnection

- PhysicsScientific Reports
- 2015

It is shown that the writhe is conserved under anti-parallel reconnection, which means that any deviation from helicity conservation is entirely due to the intrinsic twist inserted or deleted locally at the reconnection site.

The experimental spatial power spectrum of the velocity fluctuations in a von Kármán flow is measured, in a wide range of Reynolds numbers, 102 < Re < 106, for the first time without using the Taylor…

This work presents the first experimental observations of reconnection between quantized vortices in superfluid helium by imaging micrometer-sized solid hydrogen particles trapped on quantized vortex cores and inferring the occurrence of reconnections from the motions of groups of recoiling particles.
