Two mechanisms of modulation of very-large-scale motions by inertial particles in open channel flow

G Wang, DH Richter - Journal of Fluid Mechanics, 2019 - cambridge.org
Very-large-scale motions (VLSMs) and large-scale motions (LSMs) coexist at moderate
Reynolds numbers in a very long open channel flow. Direct numerical simulations two-way …

Evidence of preferential swee** during snow settling in atmospheric turbulence
