Universal anomalous diffusion of weakly damped particles
Vlad Bezuglyy, Michael Wilkinson, Bernhard Mehlig
We show that anomalous diffusion arises in two different models for the motion of randomly forced and weakly damped particles: one is a generalisation of the Ornstein-Uhlenbeck pro…
Poincare Indices of Rheoscopic Visualisations
Vlad Bezuglyy, Bernhard Mehlig, Michael Wilkinson
Suspensions of small anisotropic particles, termed 'rheoscopic fluids', are used for flow visualisation. By illuminating the fluid with light of three different colours, it is poss…
Multiple regimes of diffusion
B. Mehlig, M. Wilkinson, V. Bezuglyy +2
We consider the diffusion of independent particles experiencing random accelerations by a space- and time-dependent force as well as viscous damping. This model can exhibit several…
Stokes trapping and planet formation
M. Wilkinson, B. Mehlig, V. Uski
It is believed that planets are formed by aggregation of dust particles suspended in the turbulent gas forming accretion disks around developing stars. We describe a mechanism, ter…
On the Aggregation of Inertial Particles in Random Flows
B. Mehlig, M. Wilkinson, K. Duncan +2
We describe a criterion for particles suspended in a randomly moving fluid to aggregate. Aggregation occurs when the expectation value of a random variable is negative. This random…
Caustics in turbulent aerosols
M. Wilkinson, B. Mehlig
Networks of caustics can occur in the distribution of particles suspended in a randomly moving gas. These can facilitate coagulation of particles by bringing them into close proxim…
