Linear Inviscid Damping and Vorticity Depletion for Shear Flows

Annals of PDE, 2017
In this paper, we prove the linear damping for the 2-D Euler equations around a class of shear flows under the assumption that the linearized operator has no embedding eigenvalues.

Vortex Axisymmetrization, Inviscid Damping, and Vorticity Depletion in the Linearized 2D Euler Equations

Annals of PDE, 2017
Coherent vortices are often observed to persist for long times in turbulent 2D flows even at very high Reynolds numbers and are observed in experiments and computer simulations to potentially be asymptotically stable in a weak sense for the 2D Euler ...

Streamlines, vorticity lines, and vortices

29th Aerospace Sciences Meeting, 1991
The properties of vortical flows are studied using both theoretical analysis and computational flow fields. The consequences of two definitions of the vortex core, a minimum in the streamline curvature and a maximum in the normalized helicity, are examined.

Shock formation in solutions to the 2D compressible Euler equations in the presence of non-zero vorticity

Inventiones Mathematicae, 2016
We study the Cauchy problem for the compressible Euler equations in two spatial dimensions under any physical barotropic equation of state except that of a Chaplygin gas.
