Slow decay of concentration variance due to no-slip walls in chaotic mixing
Emmanuelle Gouillart, Olivier Dauchot, Bérengère Dubrulle +2
Chaotic mixing in a closed vessel is studied experimentally and numerically in different 2-D flow configurations. For a purely hyperbolic phase space, it is well-known that concent…
A turbulent model of torque in von Karman swirling flow
Nicolas Leprovost, Louis Marié, Bérengère Dubrulle
A stochastic model is derived to predict the turbulent torque produced by a swirling flow. It is a simple Langevin process, with a colored noise. Using the unified colored noise ap…
Dynamics and thermodynamics of axisymmetric flows: I. Theory
Nicolas Leprovost, Bérengère Dubrulle, Pierre-Henri Chavanis
We develop new variational principles to study stability and equilibrium of axisymmetric flows. We show that there is an infinite number of steady state solutions. We show that the…
