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,…
Relative accelerations characterize the hydrodynamic interaction of cloud droplets
R. V. Kearney, G. P. Bewley
Water droplets coalesce into larger ones in atmospheric clouds to form rain. But droplets on collision courses do not always coalesce due to the cushioning effects of the air betwe…
Bifurcations in droplet collisions
A. Dubey, K. Gustavsson, G. Bewley +1
Saffman and Turner (1957) argued that the collision rate for droplets in turbulence increases as the turbulent strain rate increases. But the numerical simulations of Dhanasekaran…
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…
Turbulence explains the accelerations of an eagle in natural flight
Kasey M. Laurent, Bob Fogg, Tobias Ginsburg +5
Turbulent winds and gusts fluctuate on a wide range of timescales from milliseconds to minutes and longer, a range that overlaps the timescales of avian flight behavior, yet the im…
How to Extract Energy from Turbulence in Flight by Fast Tracking
Scott A. Bollt, Gregory P. Bewley
We analyze a way to make flight vehicles harvest energy from homogeneous turbulence by fast tracking in the way that falling inertial particles do. Mean airspeed increases relative…
