Effects of the resonant magnetic perturbation on turbulent transport
Madalina Vlad, Florin Spineanu
The effects of the resonant magnetic perturbations (RMPs) on the turbulent transport are analyzed in the framework of the test particle approach using a semi-analytical method. The…
A MHD invariant and the confinement regimes in Tokamak
Florin Spineanu, Madalina Vlad
Fundamental Lagrangian, frozen-in and topological invariants can be useful to explain systematic connections between plasma parameters. At high plasma temperature the dissipation i…
Geometrical aspects of the interaction between expanding clouds and environment
F. Spineanu, M. Vlad
This work is intended to be a contribution to the study of the morphology of the rising convective columns, for a better representation of the processes of entrainment and detrainm…
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…
The filamentation of the laser beam as a labyrinth instability
Florin Spineanu, Madalina Vlad
At incident powers much higher than the threshold for filamentation a pulse from a high-power laser generates in the transversal plane a complex structure. It consists of randomly…
Effect of density changes on tokamak plasma confinement
F. Spineanu, M. Vlad
A change of the particle density (by gas puff, pellets or impurity seeding) during the plasma discharge in tokamak produces a radial current and implicitly a torque and rotation th…
