Mixing and reaction efficiency in closed domains
S. Berti, D. Vergni, F. Visconti +1
We present a numerical study of mixing and reaction efficiency in closed domains. In particular we focus our attention on laminar flows. In the case of inert transport the mixing p…
Large-scale effects on meso-scale modeling for scalar transport
M. Cencini, A. Mazzino, S. Musacchio +1
The transport of scalar quantities passively advected by velocity fields with a small-scale component can be modeled at meso-scale level by means of an effective drift and an effec…
Thin front propagation in random shear flows
M. Chinappi, M. Cencini, A. Vulpiani
Front propagation in time dependent laminar flows is investigated in the limit of very fast reaction and very thin fronts, i.e. the so-called geometrical optics limit. In particula…
Turbulence and coarsening in active and passive binary mixtures
S. Berti, G. Boffetta, M. Cencini +1
Phase separation between two fluids in two-dimensions is investigated by means of Direct Numerical Simulations of coupled Navier-Stokes and Cahn-Hilliard equations. We study the ph…
Properties making a chaotic system a good Pseudo Random Number Generator
Massimo Falcioni, Luigi Palatella, Simone Pigolotti +1
We discuss two properties making a deterministic algorithm suitable to generate a pseudo random sequence of numbers: high value of Kolmogorov-Sinai entropy and high-dimensionality.…
