Critical charges for droplet collisions
A. Dubey, G. P. Bewley, K. Gustavsson +1
The collision efficiency of uncharged micron-sized water droplets in air is determined by the breakdown of hydrodynamics at droplet separations of the order of the mean-free path,…
Collisions of micron-sized, charged water droplets in still air
G. Magnusson, A. Dubey, R. Kearney +2
We investigate the effect of electrical charge on collisions of hydrodynamically interacting, micron-sized water droplets settling through quiescent air. The relative dynamics of c…
Alignment statistics of rods with the Lagrangian stretching direction in a channel flow
Z. Cui, A. Dubey, L. Zhao +1
In homogeneous isotropic turbulence, slender rods are known to align with the Lagrangian stretching direction. However, how the degree of alignment depends on the aspect ratio of t…
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…
Star Formation in the First Galaxies I: Collapse Delayed by Lyman-Werner Radiation
Chalence Safranek-Shrader, Meghann Agarwal, Christoph Federrath +3
We investigate the process of metal-free star formation in the first galaxies with a high-resolution cosmological simulation. We consider the cosmologically motivated scenario in w…
