Hidden Lagrangian coherence and memory effects in the statistics of Hamiltonian motions
Madalina Vlad, Dragos Iustin Palade, Florin Spineanu
This paper is focused on the coherent effects that appear in tracer statistics in two-dimensional incompressible turbulence in the presence of an average velocity. We show that thi…
Trajectory statistics and turbulence evolution
M. Vlad, F. Spineanu
The aim of this paper is to understand the tendency to organization of the turbulence in two-dimensional ideal fluids. We show that nonlinear processes as inverse cascade of the en…
Field theoretical formulation of the asymptotic relaxation states of two-dimensional ideal fluids
Florin Spineanu, Madalina Vlad
The ideal incompressible fluid in two dimensions (Euler fluid) evolves at relaxation from turbulent states to highly coherent states of flow. For the case of double spatial periodi…
Physical aspects of the field-theoretical description of two-dimensional ideal fluids
Florin Spineanu, Madalina Vlad
The two-dimensional ideal (Euler) fluids can be described by the classical fields of streamfunction, velocity and vorticity and, in an equivalent manner, by a model of discrete poi…
Field theoretical approach to the description of the coherent structures in 2D fluids and plasmas
Florin Spineanu, Madalina Vlad
Evolving from turbulent states the 2D fluids and the plasmas reach states characterized by a high degree of order, consisting of few vortices. These asymptotic states represent a s…
Exact vortex solution of the Jacobs-Rebbi equation for ideal fluids
F. Spineanu, M. Vlad
The Jacobs-Rebbi equation arises in many contexts where vortical motion in two-dimensional ideal media is investigated. Alternatively, it can be derived in the Abelian Higgs field…
