Instability and disintegration of vortex rings during head-on collisions and wall interactions
Aakash Mishra, Alain Pumir, Rodolfo Ostilla-Mónico
The head-on collision of two vortex rings can produce diverse phenomena: a tiara of secondary rings, vortex sheets which flatten and interact iteratively, or the violent disintegra…
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…
Frictional boundary layer effect on vortex condensation in rotating turbulent convection
Andrés J. Aguirre Guzmán, Matteo Madonia, Jonathan S. Cheng +3
We perform direct numerical simulations of rotating Rayleigh--Bénard convection of fluids with low () and high () Prandtl numbers in a horizontally periodic layer wit…
Angular momentum transport and flow organisation in Taylor-Couette flow at radius ratio of
Andreas Froitzheim, Sebastian Merbold, Rodolfo Ostilla-Mónico +1
We experimentally and numerically investigate the angular momentum transport in turbulent Taylor-Couette flow for independently rotating cylinders at a small radius ratio of $η=0.3…
Fluctuation-induced forces in homogeneous isotropic turbulence
Vamsi Spandan, Daniel Putt, Rodolfo Ostilla-Mónico +1
Understanding force generation in non-equilibrium systems is a significant challenge in statistical physics. We uncover a surprising fluctuation-induced force between two plates im…
Life stages of wall-bounded decay of Taylor-Couette turbulence
Rodolfo Ostilla-Mónico, Xiaojue Zhu, Vamsi Spandan +2
The decay of Taylor-Couette turbulence, i.e~the flow between two coaxial and independently rotating cylinders, is numerically studied by instantaneously stopping the forcing from a…
The effect of roll number on the statistics of turbulent Taylor-Couette flow
Rodolfo Ostilla-Mónico, Detlef Lohse, Roberto Verzicco
A series of direct numerical simulations in large computational domains has been performed in order to probe the spatial feature robustness of the Taylor rolls in turbulent Taylor-…
