Evolution of hairpin vortices in a shear flow [PDF]

open access: yes
Recent experimental studies suggest that the hairpin vortex plays an important (and perhaps dominant) role in the dynamics of turbulent flows near walls. In this study a numerical procedure is developed to allow the accurate computation of the trajectory

Quantitative ring current model: Overview and comparison with observations [PDF]

open access: yes, 1999
This paper describes a new quantitative ring current model that solves temporal evolution of the ion distribution in the magnetosphere by tracing the ion drift motion.

Singularities of Euler flow? Not out of the blue! [PDF]

open access: yes, 2002
Does three-dimensional incompressible Euler flow with smooth initial conditions develop a singularity with infinite vorticity after a finite time? This blowup problem is still open.

Strong illposedness of the incompressible Euler equation in integer $C^m$ spaces

open access: yes, 2014
We consider the $d$-dimensional incompressible Euler equations. We show strong illposedness of velocity in any $C^m$ spaces whenever $m\ge 1$ is an \emph{integer}.

Fluid flow estimation with multiscale ensemble filters based on motion measurements under location uncertainty [PDF]

open access: yes, 2013
International audienceThis paper proposes a novel multi-scale fluid flow data assimilation approach, which integrates and complements the advantages of a Bayesian sequential assimilation technique, the Weighted Ensemble Kalman filter (WEnKF).

Theory of Decay of Superfluid Turbulence intheLow-Temperature Limit [PDF]

open access: yes, 2018
We review the theory of relaxational kinetics of superfluid turbulence—a tangle of quantized vortex lines—in the limit of very low temperatures when the motion of vortices is conservative.

Aerodynamic Theory of the Oscillating Wing of Finite Span [PDF]

open access: yes, 1942
The theory of the oscillating airfoil of infinite span with two-dimensional flow has been developed to a high degree of completeness (ref. 4, 7) In the present theory the oscillating airfoil of finite span is considered with the purpose of introducing
