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…
Enhanced transport of flexible fibers by pole vaulting in turbulent wall-bounded flow
Jeremie Bec, Christophe Brouzet, Christophe Henry
Long, flexible fibers transported by a turbulent channel flow sample non-linear variations of the fluid velocity along their length. As the fibers tumble and collide with the bound…
Particle resuspension: challenges and perspectives for future models
Christophe Henry, Jean-Pierre Minier, Sara Brambilla
The purpose of this review is to analyze the physics at play in particle resuspension in order to bring insights into the rich complexity of this common but challenging concern. Fo…
Lagrangian stochastic model for the orientation of inertialess spheroidal particles in turbulent flows: an efficient numerical method for CFD approach
Lorenzo Campana, Mireille Bossy, Christophe Henry
In this work, we propose a model for the orientation of inertialess spheroidal particles suspended in turbulent flows. This model consists in a stochastic version of the Jeffery eq…
Stretching and buckling of small elastic fibers in turbulence
Sofia Allende, Christophe Henry, Jeremie Bec
Small flexible fibers in a turbulent flow are found to be most of the time as straight as stiff rods. This is due to the cooperative action of flexural rigidity and fluid stretchin…
Particle resuspension from complex surfaces: current knowledge and limitations
Christophe Henry
This review explores particle resuspension from surfaces due to fluid flows. The objective of this review is to provide a general framework and terminology for particle resuspensio…
Tumbling dynamics of inertial chains in extensional flow
Christophe Henry, Giorgio Krstulovic, Jérémie Bec
The dynamics of elongated inertial particles in an extensional flow is studied numerically by performing simulations of freely jointed bead-rod chains. The coil-stretch transition…
Inelastic accretion of inertial particles by a towed sphere
Robin Vallée, Christophe Henry, Elie Hachem +1
The problem of accretion of small particles by a sphere embedded in a mean flow is studied in the case where the particles undergo inelastic collisions with the solid object. The c…
