Statistical orientation and distribution of columnar ice crystals in turbulent flows
A. Pumir, M. Z. Sheikh, K. Gustavsson +3
We study the motion of columnar ice crystals that form in clouds over a range of low temperature. Our focus here is on elongated ice crystals, which are smaller than the size of th…

Importance of fluid inertia for the orientation of spheroids settling in turbulent flow
Muhammad Zubair Sheikh, Kristian Gustavsson, Diego Lopez +4
How non-spherical particles orient as they settle in a flow has important practical implications in a number of scientific and engineering problems. In a quiescent fluid, a slowly…

Theory for the effect of fluid inertia on the orientation of a small particle settling in turbulence
K. Gustavsson, M. Z. Sheikh, D. Lopez +3
Ice crystals settling through a turbulent cloud are rotated by turbulent velocity gradients. In the same way, turbulence affects the orientation of aggregates of organic matter set…
