Simple models of non-Gaussian statistics for a turbulently advected passive scalar.

We study the probability distribution of a passive scalar undergoing turbulent mixing in the presence of a mean scalar gradient. Kerstein's model, which describes the turbulent mixing process as a… Expand

A complete analytic solution is presented for the selection of symmetric Saffman-Taylor fingers, in the small\char21{}surface-tension limit. In a previous paper [Combescot et al., Phys. Rev. Lett.… Expand

Finite-time singularities in the axisymmetric three-dimension Euler equations.

For pointlike singularities localized well away from the symmetry axis, axisymmetric flows with swirl are arbitrarily well approximated by two-dimensional Boussinesq convection. An adaptive mesh… Expand

Numerical simulation of interacting vortex tubes.

The structure of the cores of interacting vortex tubes in three-dimensional incompressible hydrodynamics has been simulated by a pseudospectral method. A fast reconnection is observed for Reynolds… Expand

Vortex morphology and Kelvin's theorem.

The Clebsch form of the Euler equations provides an intuitive picture as to how the circulation constraints direct the spatial organization of vorticity and favor the formation of vortex sheets.… Expand
