Aggregation and fragmentation dynamics in random flows: From tracers to inertial aggregates
Ksenia Guseva, Ulrike Feudel
We investigate aggregation and fragmentation dynamics of tracers and inertial aggregates in random flows leading to steady state size distributions. Our objective is to elucidate t…
Edge anisotropy and the geometric perspective on flow networks
Nora Molkenthin, Hannes Kutza, Liubov Tupikina +5
Spatial networks have recently attracted great interest in various fields of research. While the traditional network-theoretic viewpoint is commonly restricted to their topological…
History effects in the sedimentation of light aerosols in turbulence: the case of marine snow
Ksenia Guseva, Anton Daitche, Ulrike Feudel +1
We analyze the effect of the Basset history force on the sedimentation of nearly neutrally buoyant particles, exemplified by marine snow, in a three-dimensional turbulent flow. Par…
Numerical simulations of aggregate breakup in bounded and unbounded turbulent flows
Matthaus U. Babler, Luca Biferale, Luca Brandt +8
Breakup of small aggregates in fully developed turbulence is studied by means of direct numerical simulations in a series of typical bounded and unbounded flow configurations, such…
What Determines Size Distributions of Heavy Drops in a Synthetic Turbulent Flow?
Jens C. Zahnow, Ulrike Feudel
We present results from an individual particle based model for the collision, coagulation and fragmentation of heavy drops moving in a turbulent flow. Such a model framework can he…
Particle-based modelling of aggregation and fragmentation processes: Fractal-like aggregates
Jens C. Zahnow, Joeran Maerz, Ulrike Feudel
The incorporation of particle inertia into the usual mean field theory for particle aggregation and fragmentation in fluid flows is still an unsolved problem. We therefore suggest…
