Importance of fluid inertia for the orientation of spheroids settling in turbulent flow

Article dans J. Fluid. Mech. (2020)

Importance of fluid inertia for the orientation of spheroids settling in turbulent flow

Muhammad Zubair Sheikh, Kristian Gustavsson, Diego Lopez, Emmanuel Lévêque, Bernhard Mehlig, Alain Pumir & Aurore Naso

How non-spherical particles orient as they settle in a flow has important practical implications in a number of scientific and engineering problems. In a quiescent fluid, a slowly settling (...)

Sudden diffusion of turbulent mixing layers in weakly coupled plasmas under compression

Article dans Phys. Rev. E (2019)

Sudden diffusion of turbulent mixing layers in weakly coupled plasmas under compression

Giovanni Viciconte, Benoît-Joseph Gréa, Fabien S. Godeferd, Philippe Arnault & Jean Clérouin

The rapid growth of viscosity driven by temperature increase in turbulent plasmas under compression induces a sudden dissipation of kinetic energy, eventually leading to the relaminarization of (...)

The turbulent Faraday instability in miscible fluids

Article dans J. Fluid. Mech. (2020)

The turbulent Faraday instability in miscible fluids

Antoine Briard, Louis Gostiaux & Benoît-Joseph Gréa

Experiments of a turbulent mixing zone created by the Faraday instability at the statically stable interface between salt and fresh water are presented. The two-layer system, contained in a (...)

Smoke control in tunnel with a transverse ventilation system : An experimental study

Article dans Building and Environment (2020)

Smoke control in tunnel with a transverse ventilation system : An experimental study

Fateh Chaabat, Pietro Salizzoni, Mathieu Creyssels, Antoine Mos, Joy Wingrave, Horacio Correia, Massimo Marro

We carried out a series of experiments in a small-scale tunnel to study the confinement of smoke flow between two exhaust vents located on either side of a buoyant source placed at ground level (...)

Storm‐induced turbidity currents on a sediment‐starved shelf : Insight from direct monitoring and repeat seabed mapping of upslope migrating bedforms

Article dans Sedimentology (2019)

Storm‐induced turbidity currents on a sediment‐starved shelf : Insight from direct monitoring and repeat seabed mapping of upslope migrating bedforms

Alexandre Normandeau, Daniel Bourgault, Urs Neumeier, Patrick Lajeunesse, Guillaume St‐Onge, Louis Gostiaux & Cédric Chavanne

The monitoring of turbidity currents enables accurate internal structure and timing of these flows to be understood. Without monitoring, triggers of turbidity currents often remain hypothetical (...)

Linking dissipation, anisotropy, and intermittency in rotating stratified turbulence at the threshold of linear shear instabilities

Article dans Phys. Fluids (2019)

Linking dissipation, anisotropy, and intermittency in rotating stratified turbulence at the threshold of linear shear instabilities

Annick Pouquet, Duane Rosenberg & Raffaele Marino

Analyzing a large database of high-resolution three-dimensional direct numerical simulations of decaying rotating stratified flows, we show that anomalous mixing and dissipation, marked (...)

Effect of high frequency vibrations on PV silicon purification

Article dans Journal of crystal growth (2020)

Effect of high frequency vibrations on PV silicon purification

Samia Bouarab, Faiza Mokhtari, Slim Kaddeche, Daniel Henry, Valéry Botton, Abdessamed Medelfef

Silicon purification for photovoltaic applications is a crucial challenge to improve the energy production performance of solar panels. In the present work, we focus on the metallurgical grade (...)

Experimental investigation of vertical turbulent transport of a passive scalar in a boundary layer : Statistics and visibility graph analysis

Article dans Phys. Rev. Fluids (2019)

Experimental investigation of vertical turbulent transport of a passive scalar in a boundary layer : Statistics and visibility graph analysis

G. Iacobello, M. Marro, L. Ridolfi, P. Salizzoni & S. Scarsoglio

The dynamics of a passive scalar plume in a turbulent boundary layer is experimentally investigated via vertical turbulent transport time series. Experimental data are acquired in a rough-wall (...)

Assessing the nonequilibrium of decaying turbulence with reversed initial fields

Article dans Phys. Rev. Fluids (2019)

Assessing the nonequilibrium of decaying turbulence with reversed initial fields

F. Liu, L. P. Lu, Wouter J. T. Bos & Le Fang

Recently, it was observed that in nonequilibrium turbulent flows the normalized dissipation rate depends in a fairly universal way on the Reynolds number of the flow. To assess theoretical (...)

Diffusiophoresis, Batchelor scale and effective Péclet numbers

Article dans J. Fluid. Mech. (2019)

Diffusiophoresis, Batchelor scale and effective Péclet numbers

Florence Raynal & Romain Volk

We study the joint mixing of colloids and salt released together in a stagnation point or in a globally chaotic flow. In the presence of salt inhomogeneities, the mixing time is strongly modified (...)
