Aggregation, breakup, and size-dependent transport in a turbulent channel flow with cohesive particles
Alexandre D. Leonelli, Lukas Widmer, Eckart Meiburg
Due to attractive inter-particle forces, cohesive particles suspended in turbulence undergo a complex process of aggregation, breakup, and restructuring. Despite a growing body of…
On the biogenic hydrodynamic transport of upward and downward cruising copepods
Yunxing Su, Rui Zhu, Eckart Meiburg +1
Mesozooplankton aggregations undergoing vertical migrations in the upper ocean have been hypothesized to have an important role in the redistribution of carbon, nutrients, and oxyg…
Gravity-driven flux of particles through apertures
Ram Sudhir Sharma, Alexandre Leonelli, Kevin Zhao +2
The gravity-driven discharge of granular material through an aperture is a fundamental problem in granular physics and is classically described by empirical laws with different fit…
Gravity current propagating against constant and pulsating counter flows
Cem Bingol, Matias Duran-Matute, Eckart Meiburg +1
This paper describes the evolution of two-dimensional (2D) gravity currents that flow against a horizontally uniform laminar pulsating flow. We study the effect of opposing mean fl…
Long-term microgravity experiments reveal a new mechanism for particle aggregation in suspension
Fabian Kleischmann, Bernhard Vowinckel, Eckart Meiburg +1
Microgravity experiments on board the International Space Station, combined with particle-resolved direct numerical simulations, were conducted to investigate the long-term floccul…
