Rheology of concentrated suspension of fibers with load dependent friction coefficient
Monsurul Khan, Rishabh V. More, Arash Alizad Banaei +2
We numerically investigate the effects of fiber aspect ratio, roughness, flexibility, and flow inertia on the rheology of concentrated suspensions. We perform direct numerical simu…
Orientation instability of settling spheroids in a linearly density stratified fluid
Rishabh V. More, Mehdi N. Ardekani, Luca Brandt +1
Much work has been done to understand the settling dynamics of spherical particles in a homogeneous and a stratified fluid. However, the effects of shape anisotropy on the settling…
Interface-resolved simulations of small inertial particles in turbulent channel flow
Pedro Costa, Luca Brandt, Francesco Picano
We present a direct comparison between interface-resolved and one-way-coupled point-particle direct numerical simulations (DNS) of gravity-free turbulent channel flow laden with sm…
The role of wetting on the flow of two immiscible fluids in porous media
Armin Shahmardi, Salar Zamani Salimi, Outi Tammisola +2
We study the role of the capillary number, and of the surface wettability on the dynamics of the interface between an invading and a defending phase in a porous medium by mean…
