Effects of permeability on hindered settling of porous particles
Alexander Metelkin, Bernhard Vowinckel
We investigate the settling behavior of suspensions of highly porous and permeable particles in the viscous regime using particle-resolved direct numerical simulations (DNS). The s…
A Data-Driven Approach for Predicting Hydrodynamic Forces on Spherical Particles Using Volume Fraction Representations
Alexander Metelkin, Sam Jacob Jacob, Bernhard Vowinckel
Particle-laden flows are simulated at various scales using numerical techniques that range from particle-resolved Direct Numerical Simulations (pr-DNS) for small-scale systems to L…
On the parameters of common settling velocity models for porous sediment aggregates
Alexander Metelkin, Bernhard Vowinckel
The settling behavior of sediment aggregates is a critical factor influencing the transport of fine-grained sediments in riverine and marine environments. Due to the small size and…
Particle resuspension from complex multilayer deposits by laminar flows: statistical analysis and modeling
Hao Liu, Mireille Bossy, Bernhard Vowinckel +1
Particle resuspension refers to the physical process by which solid particles deposited on a surface are, first, detached and, then, entrained away by the action of a fluid flow. I…
Pairwise interaction of spherical particles aligned in oscillatory flow
Fabian Kleischmann, Paolo Luzzatto-Fegiz, Eckart Meiburg +1
We present a systematic simulation campaign to investigate the pairwise interaction of two mobile, monodisperse particles submerged in a viscous fluid and subjected to monochromati…
