Interaction of near-inertial waves with an anticyclonic vortex
Hossein A. Kafiabad, Jacques Vanneste, William R. Young
Anticyclonic vortices focus and trap near-inertial waves so that near-inertial energy levels are elevated within the vortex core. Some aspects of this process, including the nonlin…
The dispersion of spherical droplets in source-sink flows and their relevance to the COVID-19 pandemic
Cathal Cummins, Olayinka Ajayi, Felicity Mehendale +2
In this paper, we investigate the dynamics of spherical droplets in the presence of a source-sink pair flow field. The dynamics of the droplets is governed by the Maxey-Riley equat…
Inertia-gravity-wave scattering by geostrophic turbulence
Miles A. C. Savva, Hossein A. Kafiabad, Jacques Vanneste
In rotating stratified flows including in the atmosphere and ocean, inertia-gravity waves (IGWs) often coexist with a geostrophically balanced turbulent flow. Advection and refract…
Data-driven identification of the spatio-temporal structure of turbulent flows by streaming Dynamic Mode Decomposition
Rui Yang, Xuan Zhang, Philipp Reiter +3
Streaming Dynamic Mode Decomposition (sDMD) (Hemati et al., Phys. Fluids 26(2014)) is a low-storage version of Dynamic Mode Decomposition (DMD) (Schmid, J. Fluid Mech. 656 (2010)),…
On the Holton-Lindzen-Plumb model for mean flow reversals in stratified fluids
Antoine Renaud, Antoine Venaille
The Holton-Lindzen-Plumb model describes the spontaneous emergence of mean flow reversals in stratified fluids. It has played a central role in understanding the quasi-biennial osc…
Dispersion of inertial particles in cellular flows in the small-Stokes, large-Péclet regime
Antoine Renaud, Jacques Vanneste
We investigate the transport of inertial particles by cellular flows when advection dominates over inertia and diffusion, that is, for Stokes and Péclet numbers satisfying $\mathrm…
