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 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…
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…
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…
