Fluctuation relation and pairing rule for Lyapunov exponents of inertial particles in turbulence
Itzhak Fouxon, Péter Horvai
We study the motion of small particles in a random turbulent flow assuming linear law of friction. We derive a symmetry relation obeyed by the large deviations of the finite time L…
Single and two-particle motion of heavy particles in turbulence
I. Fouxon, P. Horvai
We study motion of small particles in turbulence when the particle relaxation time falls in the range of inertial time-scales of the flow. Due to inertia, particles drift relative…
Dynamo effect in the Kraichnan magnetohydrodynamic turbulence
Heikki Arponen, Peter Horvai
The existence of a dynamo effect in a simplified magnetohydrodynamic model of turbulence is considered when the magnetic Prandtl number approaches zero or infinity. The magnetic fi…
Lyapunov exponent for inertial particles in the 2D Kraichnan model as a problem of Anderson localization with complex valued potential
Peter Horvai
We exploit the analogy between dynamics of inertial particle pair separation in a random-in-time flow and the Anderson model of a quantum particle on the line in a spatially random…
Intermittent distribution of tracers advected by a compressible random flow
Jeremie Bec, Krzysztof Gawedzki, Peter Horvai
Multifractal properties of a tracer density passively advected by a compressible random velocity field are characterized. A relationship is established between the statistical prop…
Sticky behavior of fluid particles in the compressible Kraichnan model
Krzysztof Gawedzki, Peter Horvai
We consider the compressible Kraichnan model of turbulent advection with small molecular diffusivity and velocity field regularized at short scales to mimic the effects of viscosit…
