Triangular instability of a strained Batchelor vortex
A. S. P. Ayapilla, Y. Hattori, S. Le Dizès
We investigate the triangular instability of a Batchelor vortex subjected to a stationary triangular strain field generated by three satellite vortices, in the presence of weak axi…

Zonal flows driven by libration in rotating spherical shells: the case of periodic characteristic paths
Xu Chang, Jiyang He, Benjamin Favier +1
This work investigates the weakly nonlinear dynamics of internal shear layers and the mean zonal flow induced by the longitudinal libration of an inner core within a spherical shel…

Internal shear layers generated by a vertically oscillating cylinder in unbounded and bounded rotating fluids
Jiyang He, Benjamin Favier, Stéphane Le Dizès
In rotating fluids, the viscous smoothing of inviscid singular inertial waves leads to the formation of internal shear layers. In previous works, we analysed the internal shear lay…
