Abstract

The passive convection of Lagrangian points by a 2D compressible two-fluids flow is investigated numerically on a massively parallel computer. This numerical simulation concerns the Rayleigh-Taylor instability [1]. We compute the fractal dimension of this set of tracer particles located along the interface between the two fluids. A first result is that this dimension reaches a stationary value. Then this result is used to determine the effective opacity of the mixture.

In the second part we study the morphology of the mixing layer via the wavelet transform of the density field. The multifractal analysis is discussed.
