Caustic formation in a non-Gaussian model for turbulent aerosols
J. Meibohm, L. Sundberg, B. Mehlig +1
Caustics in the dynamics of heavy particles in turbulence accelerate particle collisions. The rate at which these singularities form depends sensitively on the Stokes…
Caustics in turbulent aerosols form along the Vieillefosse line at weak particle inertia
Jan Meibohm, Kristian Gustavsson, Bernhard Mehlig
Caustic singularities of the spatial distribution of particles in turbulent aerosols enhance collision rates and accelerate coagulation. Here we investigate how and where caustics…
Fractal catastrophes
J. Meibohm, K. Gustavsson, J. Bec +1
We analyse the spatial inhomogeneities ('spatial clustering') in the distribution of particles accelerated by a force that changes randomly in space and time. To quantify spatial c…
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…
Relative velocities in bidisperse turbulent suspensions
J. Meibohm, L. Pistone, K. Gustavsson +1
We investigate the distribution of relative velocities between small heavy particles of different sizes in turbulence by analysing a statistical model for bidisperse turbulent susp…
Angular velocity of a spheroid log rolling in a simple shear at small Reynolds number
J. Meibohm, F. Candelier, T. Rosén +3
We analyse the angular velocity of a small neutrally buoyant spheroid log rolling in a simple shear. When the effect of fluid inertia is negligible the angular velocity equals…
