Unmixing in Random Flows
M. Wilkinson, B. Mehlig, S. Ostlund +1
We consider particles suspended in a randomly stirred or turbulent fluid. When effects of the inertia of the particles are significant, an initially uniform scatter of particles ca…
Colliding Particles in Highly Turbulent Flows
Bernhard Mehlig, Ville Uski, Michael Wilkinson
We discuss relative velocities and the collision rate of small particles suspended in a highly turbulent fluid. In the limit where the viscous damping is very weak, we estimate the…
Strength distribution of repeatedly broken chains
Michael Wilkinson, Bernhard Mehlig
We determine the probability distribution of the breaking strength for chains of N links, which have been produced by repeatedly breaking a very long chain.
Caustic activation of rain showers
Michael Wilkinson, Bernhard Mehlig, Vlad Bezuglyy
We show quantitatively how the collision rate of droplets of visible moisture in turbulent air increases very abruptly as the intensity of the turbulence passes a threshold, due to…
Generalised Ornstein-Uhlenbeck processes
V. Bezuglyy, B. Mehlig, M. Wilkinson +2
We solve a physically significant extension of a classic problem in the theory of diffusion, namely the Ornstein-Uhlenbeck process [G. E. Ornstein and L. S. Uhlenbeck, Phys. Rev. 3…
