Asymptotic profiles and large-time behavior for 3D micropolar fluid equations with possibly vanishing spin viscosity
Lorenzo Brandolese, Pablo Braz e Silva, Adriana Valentina Busuioc +2
We consider 3D micropolar flows with possible vanishing spin viscosity and investigate the decay of the energy for large times. We compute first the exact -asymptotic profile,…
On the Role of the Viscosity Parameters in the Large Time Asymptotics of 2D Micropolar Flows
Lorenzo Brandolese, Adriana Valentina Busuioc, Dragos Iftimie +1
We investigate the role of the four viscosity parameters, in fluids where the particles possess a microstructure (micropolar flows) and are allowed to rotate in a two-dimensional s…
On the Dynamics of Point Vortices with Positive Intensities collapsing with the boundary
Martin Donati, Ludovic Godard-Cadillac, Dragos Iftimie
In this paper, we study the point-vortex dynamics with positive intensities. We show that in the half-plane and in a disk, collapses of point vortices with the boundary in finite t…
The incompressible --Euler equations in the exterior of a vanishing disk
Adriana Valentina Busuioc, Dragos Iftimie, Milton Lopes Filho +1
In this article we consider the --Euler equations in the exterior of a small fixed disk of radius . We assume that the initial potential vorticity is compactly supported and…
Long time confinement of vorticity around a stable stationary point vortex in a bounded planar domain
Martin Donati, Dragos Iftimie
In this paper we consider the incompressible Euler equation in a simply-connected bounded planar domain. We study the confinement of the vorticity around a stationary point vortex.…
On the small rigid body limit in 3D incompressible flows
Jiao He, Dragos Iftimie
We consider the evolution of a small rigid body in an incompressible viscous fluid filling the whole space. The motion of the fluid is modelled by the Navier-Stokes equations, wher…
