Superfast front propagation in reactive systems with anomalous diffusion
Rosaria Mancinelli, Davide Vergni, Angelo Vulpiani
We study a reaction diffusion system where we consider a non-gaussian process instead of a standard diffusion. If the process increments follow a probability distribution with tail…
Inverse velocity statistics in two dimensional turbulence
L. Biferale, M. Cencini, A. Lanotte +1
We present a numerical study of two-dimensional turbulent flows in the enstrophy cascade regime, with different large-scale forcings and energy sinks. In particular, we study the s…
Efficiency of a stirred chemical reaction in a closed vessel
Cristobal lopez, Davide Vergni, Angelo Vulpiani
We perform a numerical study of the reaction efficiency in a closed vessel. Starting with a little spot of product, we compute the time needed to complete the reaction in the conta…
Thin front propagation in steady and unsteady cellular flows
M. Cencini, A. Torcini, D. Vergni +1
Front propagation in two dimensional steady and unsteady cellular flows is investigated in the limit of very fast reaction and sharp front, i.e., in the geometrical optics limit. I…
