We use a Hamiltonian description for magnetic ยฎeld lines in a large aspect ratio Tokamak for describing the eect of resonant helical windings in a perturbative way, taking into account the toroidal correction. We consider the formation of chains of primary (main and satellites) and secondary islands

The large-eddy simulation is used to study fluid mixing due to Rayleigh-Taylor instability in a timedependent acceleration field. The numerical results show that the two fluids in the mixing layer move back towards their initial position if the acceleration has a sudden change in the direction durin
## Abstract A new viewpoint on the evolution of scalar dispersion in a turbulent flow is taken by considering diffusion of a passive scalar where the measuring device is stochastically positioned. This is a model of a dispersion process where mixing at small scales occurs by molecular diffusion and
We present a new technique to globally optimize stirring and mixing in three-dimensional spatially periodic laminar flows. This technique includes a recently developed mapping method and the use of an optimization method. The method gives the opportunity of the statistics of scalar dissipation for m
