Energy transfer and vortex structures: Visualizing the incompressible turbulent energy cascade
Ryan McKeown, Alain Pumir, Shmuel M. Rubinstein +2
The transfer of kinetic energy from large to small scales is a hallmark of turbulent flows. Yet, a precise mechanistic description of this transfer, which is expected to occur via…
Cascades and Reconnection in Interacting Vortex Filaments
Rodolfo Ostilla-Mónico, Ryan McKeown, Michael P. Brenner +2
At high Reynolds number, the interaction between two vortex tubes leads to intense velocity gradients, which are at the heart of fluid turbulence. This vorticity amplification come…
Turbulence generation through an iterative cascade of the elliptical instability
Ryan McKeown, Rodolfo Ostilla-Monico, Alain Pumir +2
The essence of turbulent flow is the conveyance of energy through the formation, interaction, and destruction of eddies over a wide range of spatial scales--from the largest scales…
A Cascade Leading to the Emergence of Small Structures in Vortex Ring Collisions
Ryan McKeown, Rodolfo Ostilla-Monico, Alain Pumir +2
When vortex rings collide head-on at high enough Reynolds numbers, they ultimately annihilate through a violent interaction which breaks down their cores into a turbulent cloud. We…
