Heavy particles in a persistent random flow with traps
J. Meibohm, B. Mehlig
We study a one-dimensional model for heavy particles in a compressible fluid. The fluid-velocity field is modelled by a persistent Gaussian random function, and the particles are a…

Fractal dimensions and trajectory crossings in correlated random walks
A. Dubey, J. Meibohm, K. Gustavsson +1
We study spatial clustering in a discrete, one-dimensional, stochastic, toy model of heavy particles in turbulence and calculate the spectrum of multifractal dimensions as fu…
