Effect of Particle Inertia on the Alignment of Small Ice Crystals in Turbulent Clouds
Effect of Particle Inertia on the Alignment of Small Ice Crystals in Turbulent Clouds
Small non-spherical particles settling in a quiescent fluid tend to orient so that their broad side faces down, because this is a stable fixed point of their angular dynamics at small particle Reynolds number. Turbulence randomises the orientations to some extent, and this affects the reflection patterns of polarised light …
