Statistics and dynamics of blockings with a point vortex model
Tellus: Series A, Dynamic Meteorology and Oceanography, 2018 We investigate a reduced point vortex model for statistical and dynamical analyses of atmospheric blocking phenomena. Thereby, we consider High-over-low and Omega blocking as relative equilibria of two and three point vortices.

Interactions of point vortices in the Zabusky-McWilliams model with a background flow [PDF]
, 2012 We combine a simple quasi-geostrophic flow model with the Zabusky-McWilliams theory of atmospheric vortex dynamics to address a hurricane-tracking problem of interest to the insurance industry.

Vortex Structure and Kinematics of Encased Axial Turbomachines
International Journal of Turbomachinery, Propulsion and Power, 2018 This paper models the kinematics of the vortex system of an encased axial turbomachine at part load and overload applying analytical methods. Thus far, the influence of the casing and the tip clearance on the kinematics have been solved separately.

Physical Review Research, 2020 We investigate the stability of vortices in two-dimensional Bose–Einstein condensates. In analogy with rotating space-times and with a careful account of boundary conditions, we show that the dynamical instability of multiply quantized vortices in ...

Casimir Force between Two Vortices in a Turbulent Bose–Einstein Condensate
Atoms, 2020 We consider the Casimir force between two vortices due to the presence of density fluctuations induced by turbulent modes in a Bose–Einstein condensate. We discuss the cases of unbounded and finite condensates.

The Rayleigh–Taylor instability of two-dimensional high-density vortices [PDF]
, 2005 We investigate the stability of variable-density two-dimensional isolated vortices in the frame of incompressible mixing under negligible gravity. The focus on a single vortex flow stands as a first step towards vortex interactions and turbulent mixing ...

Ellipsoidal vortices in rotating stratified fluids : beyond the quasi-geostrophic approximation [PDF]
, 2015 Support for this research has come from the UK Engineering and Physical Sciences Research Council (grant number EP/H001794/1).We examine the basic properties and stability of isolated vortices having uniform potential vorticity (PV) in a non-hydrostatic ...
