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…
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…
Front speed enhancement in cellular flows
M. Abel, M. Cencini, D. Vergni +1
The problem of front propagation in a stirred medium is addressed in the case of cellular flows in three different regimes: slow reaction, fast reaction and geometrical optics limi…
Inverse statistics of smooth signals: the case of two dimensional turbulence
L. Biferale, M. Cencini, A. Lanotte +2
The problem of inverse statistics (statistics of distances for which the signal fluctuations are larger than a certain threshold) in differentiable signals with power law spectrum,…
Front propagation in laminar flows
M. Abel, A. Celani, D. Vergni +1
The problem of front propagation in flowing media is addressed for laminar velocity fields in two dimensions. Three representative cases are discussed: stationary cellular flow, st…
